Abstract

Couplers Laser radar Optoelectronic devices Performance evaluation Perturbation methods Phased arrays Silicon photonics
In this paper three types of Silicon Photonics OPA architectures are proposed and investigated. Edge-fire optical phased array, that simplifies the design of the OPA. Second architecture is OPA with grating coupler antennas. Maximum steering angle for edge-fire OPA is ±44°, FWHM is 0.10986°. For GC OPA steering angle is ±20° and FWHM=1.003116°. Third architecture is the Slanted Grating Coupler with a FOV of 100°.
