Title:
PIC-BASED MULTICHANNEL TRANSCEIVER
Document Type and Number:
WIPO Patent Application WO/2023/225468
Kind Code:
A3
Abstract:
An optoelectronic apparatus (100, 500) includes a dual folding mirror (114, 510) mounted on a carrier substrate (112, 524) with first and second reflecting surfaces (520, 522) disposed at opposite angles. A plurality of identical photonic integrated circuits (PICs 108, 110, 320, 502, 504, 506, 508) are disposed on the carrier substrate. Each PIC includes an array of optical transceiver cells (314, 400) on a planar substrate with respective edge couplers (406) along an edge of the planar substrate, and an optical distribution tree (320) coupled to convey coherent radiation to the optical transceiver cells. A first PIC is disposed on the carrier substrate such that the edge of the first PIC is in proximity to the first reflecting surface, and a second PIC is rotated by 180° relative to the first PIC such that the edge of the second PIC is in proximity to the second reflecting surface.
