Silicon-on-Insulator Photoimpedance Sensor Using Capacitance Dispersion

Tailored Chromatic Dispersion in Silicon-on-Insulator Slot Waveguides

We investigate the chromatic dispersion properties of silicon channel slot waveguides in a broad spectral region centered at ~1.5 μm. The variation of the dispersion profile as a function of the slot fill factor, i.e., the ratio between the slot and waveguide widths, is analyzed. Two different dispersion regimes are identified. Keywordsintegrated optics; silicon photonics; dispersion.

Intensity modulation in two Mach–Zehnder interferometers using plasma dispersion in silicon-on-insulator

We present comparative measurements of two Mach–Zehnder interferometers, one with Y-junction couplers and the other with MMI couplers, both developed in siliconon-insulator technology and using plasma dispersion effect for light phase modulation. Measurements of fiber-to-fiber losses, absorption coefficient, output intensity vs. time and extinction ratio vs. frequency have been performed at λ= ...

Modeling of temperature sensor built on thin silicon on insulator using advanced carrier-mobility model

Silicon photonics beyond silicon-on-insulator

The standard platform for silicon photonics has been ridge or channel waveguides fabricated on silicon-on-insulator (SOI) wafers. SOI waveguides are so versatile and the technology built around it is so mature and popular that silicon photonics is almost regarded as synonymous with SOI photonics. However, due to several shortcomings of SOI photonics, novel platforms have been recently emerging....

Low Dispersion Integrated Michelson Interferometer on Silicon on Insulator for Optical Coherence Tomography

We present an integrated silicon Michelson interferometer for OCT fabricated with wafer scale deep UV lithography. Silicon waveguides of the interferometer are designed with GVD less than 50 ps/nm.km. The footprint of the device is 0.5 mm x 3 mm. The effect of sidewall roughness of silicon waveguides has been observed, possible solutions are discussed.
