We demonstrate the synchronization of two dissimilar silicon nitride micromechanical oscillators, that are spaced apart by a few hundred nanometers and are coupled through an optical cavity radiation field. The tunability of the optical coupling between the oscillators enables one to externally control the dynamics and switch between coupled and individual oscillation states.

Our device is based on a compact embedded microring design fabricated on a scalable SOI platform. The coexistence of close resonance spacing and high finesse (205) in a compact footprint is possible due to enhanced quality factors (30,000) resulting from the embedded configuration and the coupling-strength dependence of resonance spacing, instead of ring size. In addition, we discuss the possibility of achieving continuously mode splitting from a single-notch resonance up to 40 GHz. textcopyright 2014 Optical Society of America.<\/div>Close<\/a><\/p><\/div><\/i>https:\/\/www.osapublishing.org\/oe\/abstract.cfm?uri=oe-22-9-10430<\/a><\/li><\/i>doi:10.1364\/OE.22.010430<\/a><\/li><\/ul><\/div>Close<\/a><\/p><\/div><\/div><\/div> Malheiros-Silveira, Gilliard N; Wiederhecker, Gustavo S; Hern'andez-Figueroa, Hugo E<\/p>Dielectric resonator antenna for applications in nanophotonics<\/a> Journal Article<\/span> <\/p>In: <\/span>Optics Express, <\/span>vol. 21, <\/span>no. 1, <\/span>pp. 1234\u20131239, <\/span>2013<\/span>.<\/p>Abstract<\/a><\/span> | Links<\/a><\/span> | BibTeX<\/a><\/span><\/p>@article{Malheiros-Silveira:13,\r\ntitle = {Dielectric resonator antenna for applications in nanophotonics},\r\nauthor = {Malheiros-Silveira, Gilliard N and Wiederhecker, Gustavo S and Hern'andez-Figueroa, Hugo E},\r\nurl = {https:\/\/www.osapublishing.org\/oe\/abstract.cfm?uri=oe-21-1-1234},\r\ndoi = {10.1364\/OE.21.001234},\r\nyear = {2013},\r\ndate = {2013-01-01},\r\njournal = {Optics Express},\r\nvolume = {21},\r\nnumber = {1},\r\npages = {1234--1239},\r\nabstract = {Optical nanoantennas, especially of the dipole type, have been theoretically and experimentally demonstrated by many research groups.

Close<\/a><\/p><\/div>Optical mode-splitting is an efficient tool to shape and fine-tune the spectral response of resonant nanophotonic devices. The active control of mode-splitting, however, is either small or accompanied by undesired resonance-shifts, often much larger than the resonance splitting. We report a control mechanism that enables reconfigurable and widely tunable mode splitting while efficiently mitigating undesired resonance shifts. This is achieved by actively controlling the excitation of counter-traveling modes in coupled resonators. The transition from a large splitting (80 GHz) to a single-notch resonance is demonstrated using low-power microheaters (35 mW). We show that the spurious resonance shift in our device is only limited by thermal crosstalk, and resonance-shift-free splitting control may be achieved.<\/div>Close<\/a><\/p><\/div><\/i>http:\/\/ol.osa.org\/abstract.cfm?URI=ol-40-14-3332<\/a><\/li><\/i>doi:10.1364\/OL.40.003332<\/a><\/li><\/ul><\/div>Close<\/a><\/p><\/div><\/div><\/div> Zhang, Mian; Luiz, Gustavo; Shah, Shreyas; Wiederhecker, Gustavo; Lipson, Michal<\/p>Eliminating anchor loss in optomechanical resonators using elastic wave interference<\/a> Journal Article<\/span> <\/p>In: <\/span>Applied Physics Letters, <\/span>vol. 105, <\/span>no. 5, <\/span>2014<\/span>.<\/p>Links<\/a><\/span> | BibTeX<\/a><\/span><\/p>@article{Zhang:2014cs,\r\ntitle = {Eliminating anchor loss in optomechanical resonators using elastic wave interference},\r\nauthor = {Zhang, Mian and Luiz, Gustavo and Shah, Shreyas and Wiederhecker, Gustavo and Lipson, Michal},\r\nurl = {http:\/\/scitation.aip.org\/content\/aip\/journal\/apl\/105\/5\/10.1063\/1.4892417},\r\ndoi = {10.1063\/1.4892417},\r\nyear = {2014},\r\ndate = {2014-01-01},\r\njournal = {Applied Physics Letters},\r\nvolume = {105},\r\nnumber = {5},\r\nkeywords = {},\r\npubstate = {published},\r\ntppubtype = {article}\r\n}\r\n<\/pre><\/div>Close<\/a><\/p><\/div><\/i>http:\/\/scitation.aip.org\/content\/aip\/journal\/apl\/105\/5\/10.1063\/1.4892417<\/a><\/li><\/i>doi:10.1063\/1.4892417<\/a><\/li><\/ul><\/div>Close<\/a><\/p><\/div><\/div><\/div> Souza, Mario C M M; Barea, Luis A M; Vallini, Felipe; Rezende, Guilherme F M; Wiederhecker, Gustavo S; Frateschi, Newton C<\/p>Embedded coupled microrings with high-finesse and close-spaced resonances for optical signal processing<\/a> Journal Article<\/span> <\/p>In: <\/span>Optics Express, <\/span>vol. 22, <\/span>no. 9, <\/span>pp. 10430\u201310438, <\/span>2014<\/span>.<\/p>Abstract<\/a><\/span> | Links<\/a><\/span> | BibTeX<\/a><\/span><\/p>@article{Souza:2014ev,\r\ntitle = {Embedded coupled microrings with high-finesse and close-spaced resonances for optical signal processing},\r\nauthor = {Souza, Mario C M M and Barea, Luis A M and Vallini, Felipe and Rezende, Guilherme F M and Wiederhecker, Gustavo S and Frateschi, Newton C},\r\nurl = {https:\/\/www.osapublishing.org\/oe\/abstract.cfm?uri=oe-22-9-10430},\r\ndoi = {10.1364\/OE.22.010430},\r\nyear = {2014},\r\ndate = {2014-01-01},\r\njournal = {Optics Express},\r\nvolume = {22},\r\nnumber = {9},\r\npages = {10430--10438},\r\nabstract = {Single microring resonators have been used in applications such as wavelength multicasting and microwave photonics, but the dependence of the free spectral range with ring radius imposes a trade-off between the required GHz optical channel spacing, footprint and power consumption.

Our device is based on a compact embedded microring design fabricated on a scalable SOI platform. The coexistence of close resonance spacing and high finesse (205) in a compact footprint is possible due to enhanced quality factors (30,000) resulting from the embedded configuration and the coupling-strength dependence of resonance spacing, instead of ring size. In addition, we discuss the possibility of achieving continuously mode splitting from a single-notch resonance up to 40 GHz. textcopyright 2014 Optical Society of America.<\/div>Close<\/a><\/p><\/div><\/i>https:\/\/www.osapublishing.org\/oe\/abstract.cfm?uri=oe-22-9-10430<\/a><\/li><\/i>doi:10.1364\/OE.22.010430<\/a><\/li><\/ul><\/div>Close<\/a><\/p><\/div><\/div><\/div> Malheiros-Silveira, Gilliard N; Wiederhecker, Gustavo S; Hern'andez-Figueroa, Hugo E<\/p>Dielectric resonator antenna for applications in nanophotonics<\/a> Journal Article<\/span> <\/p>In: <\/span>Optics Express, <\/span>vol. 21, <\/span>no. 1, <\/span>pp. 1234\u20131239, <\/span>2013<\/span>.<\/p>Abstract<\/a><\/span> | Links<\/a><\/span> | BibTeX<\/a><\/span><\/p>@article{Malheiros-Silveira:13,\r\ntitle = {Dielectric resonator antenna for applications in nanophotonics},\r\nauthor = {Malheiros-Silveira, Gilliard N and Wiederhecker, Gustavo S and Hern'andez-Figueroa, Hugo E},\r\nurl = {https:\/\/www.osapublishing.org\/oe\/abstract.cfm?uri=oe-21-1-1234},\r\ndoi = {10.1364\/OE.21.001234},\r\nyear = {2013},\r\ndate = {2013-01-01},\r\njournal = {Optics Express},\r\nvolume = {21},\r\nnumber = {1},\r\npages = {1234--1239},\r\nabstract = {Optical nanoantennas, especially of the dipole type, have been theoretically and experimentally demonstrated by many research groups.

In radio frequencies and microwaves a category of antenna known as dielectric resonator antenna (DRA), whose radiant element is a dielectric resonator (DR), has been designed for several applications, including satellite and radar systems. In this letter, we explore the possibilities and advantages to design nano DRAs (NDRAs), i. e., DRAs for nanophotonics applications. Numerical demonstrations showing the fundamental antenna parameters for a circular cylindrical NDRA type have been carried out for the short (S), conventional (C), and long (L) bands of the optical communication spectrum. textcopyright 2013 Optical Society of America.<\/div>Close<\/a><\/p><\/div><\/i>https:\/\/www.osapublishing.org\/oe\/abstract.cfm?uri=oe-21-1-1234<\/a><\/li><\/i>doi:10.1364\/OE.21.001234<\/a><\/li><\/ul><\/div>Close<\/a><\/p><\/div><\/div><\/div> Zhang, Mian; Wiederhecker, Gustavo S; Manipatruni, Sasikanth; Barnard, Arthur; McEuen, Paul; Lipson, Michal<\/p>Synchronization of Micromechanical Oscillators Using Light<\/a> Journal Article<\/span> <\/p>In: <\/span>Phys.
