Micro-dispenser based optical packaging scheme for grating couplers

Abstract

In this thesis, a design concept has proposed where several micro-lenses can be printed on grating couplers through micro-dispenser-based printing method. This method not only ensures excellent efficiency but is also feasible for easy and fast fabrication process. The author demonstrates the optical property of the proposed device in terms of both incoming and outgoing beam to the device. The device provides high angle tolerance as well as a remarkable resolution in the far-field.
