Compact Ring Resonator Enhanced Silicon-MSM Photodetector in SiN-on-SOI Platform
Avijit Chatterjee, Saumitra Sam, Sujit Kumar Sikdar +1
We present a compact on-chip resonator enhanced silicon-MSM photodetector in wavelength band for communication and lab-on-chip bio-sensing applications. We report the hi…
Alignment Tolerant Broadband Compact Taper for Low-Loss Coupling to a Silicon-on-Insulator Photonic Wire Waveguide
Purnima Sethi, Shankar Kumar Selvaraja
We experimentally demonstrate a broadband, fabrication tolerant, CMOS compatible compact silicon waveguide taper (34.2 um) in silicon-on-insulator wire waveguides. The taper works…
Mitigation of carrier induced optical bistability in silicon ring resonators
Vadivukkarasi Jeyaselvan, Shankar Kumar Selvaraja
We present a detailed study of electrical and optical generated free carrier on the spectral characteristics of a silicon microring modulator. The spectral distortion generated due…
High-speed waveguide integrated silicon photodetector on a SiN-SOI platform for short reach datacom
Avijit Chatterjee, Saumitra, Sujit Kumar Sikdar +1
We present waveguide integrated high-speed Si photodetector integrated with silicon nitride (SiN) waveguide on SOI platform for short reach data communication in 850 nm wavelength…
Generation of tunable, high repetition rate optical frequency combs using on-chip silicon modulators
Kp Nagarjun, Vadivukarassi Jeyaselvan, Shankar Kumar Selvaraja +1
We experimentally demonstrate tunable, highly-stable frequency combs with high repetition-rates using a single, charge injection based silicon PN modulator. In this work, we demons…
All-optical wavelength multicasting in quadruple resonance-split coupled Silicon microring cavity
Awanish Pandey, Shankar Kumar Selvaraja
We demonstrate an all-optical four-channel wavelength multicasting in a coupled Silicon microring resonator system. The scheme is based on two-photon absorption induced free carrie…
