Two-dimensional optical beam steering using an InP photonic integrated circuit has been demonstrated. Lateral beam steering controlled by a 1-D phased array has been made easier through on-chip… (More)
We demonstrate broadband comb-line generation from an integrated multiple quantum well InGaAsP/InP passively mode-locked laser (MLL) with a gain flattening filter (GFF) based on an asymmetric… (More)
We demonstrated a 30GHz integrated InGaAsP/InP ring mode-locked laser with a gain flattening filter that doubles the locking bandwidth and decreases the pulse width from 840fs to 620fs.
We demonstrate photonic circuits monolithically integrated on an InP-based platform for use in coherent communication links. We describe a technology platform that allows for the integration of… (More)
We present the theory and design of a tunable gain-flattening filter for integrated mode-locked lasers (MLLs). The filter provides the inverse of the semiconductor spectral gain profile and produces… (More)
InP photonic integrated circuit for 2D (5°×10°) optical beam steering has been demonstrated for the first time. Design, fabrication, and preliminary results are presented.
2D optical beam steering through an InP photonic integrated circuit with on-chip tunable laser source has been demonstrated for the first time.
We compare comb-line generation from a 30 GHz gain flattened ring mode-locked laser and two standard 30 GHz ring mode-locked lasers. The gain flattened ring has a 1.32 THz spectral width whereas the… (More)
Optical beam steering through an InP photonic integrated circuit has been improved in term of side-lobe suppression (13dB from -14° to 14° around the peak) and steering angle (10° by 28nm wavelength… (More)
Optical beam steering controlled by an array of phase shifters from an InP photonic integrated circuit has been demonstrated with the help from on-chip monitors.
