چکیده
We report the first demonstration of integrated electro-optic (EO) phase shifters based on racetrack microresonators a 3C-silicon-carbide-on-insulator (SiCOI) platform working at near-infrared (NIR) wavelengths. By applying DC voltage in crystalline axis perpendicular to waveguide plane, we have observed optical shifts from whose loaded quality (Q) factors are ~ 30,000. show length-product (V${\pi}$${\cdot}$L${\pi}$) 118 V${\cdot}$cm, which corresponds an EO coefficient r$_{41}$ 2.6 pm/V. The SiCOI can be used realize tunable SiC photonic devices that desirable for applications nonlinear and quantum photonics over wide bandwidth covers visible infrared

متن کاملCarrier-injection-based electro-optic modulator on silicon-on-insulator with a heterogeneously integrated III-V microdisk cavity.
A compact electro-optic modulator on silicon-on-insulator is presented. The structure consists of a III-V microdisk cavity heterogeneously integrated on a silicon-on-insulator wire waveguide. By modulating the loss of the active layer included in the cavity through carrier injection, the power of the transmitted light at the resonant wavelength is modulated; approximately 10 dB extinction ratio...

Using a newly proposed augmented low-index-guiding scheme with silicon nitride/silicon dual-core waveguide, we have designed, fabricated, and characterized a transverse electric (TE) to transverse magnetic (TM) and TM-to-TE compact polarization rotator. The polarization rotation is realized in an asymmetric directional coupler. The measured peak conversion efficiencies for the TE-to-TM and TM-t...
