Abstract

Photonic structures including multiple input/output optical couplers and methods of forming such photonic structures. The photonic structure comprises a light source and a photonics chip including a semiconductor substrate. The photonic structure further comprises a first mirror disposed at a first height relative to a top surface of the semiconductor substrate and a second mirror disposed at a second height relative to the top surface of the semiconductor substrate. The first mirror is configured to reflect first light from the light source to the photonics chip, and the second mirror is configured to reflect second light from the light source to the photonics chip. The first mirror is disposed between the second mirror and the light source, and the second height is different from the first height.
