摘要
High-channel-count optical transceivers can be implemented in photonic integrated circuits (PICs) with shared lasers, splitting the light of each laser between multiple lanes prior to modulation. To reduce waveguide crossings in such PICs, transmitter and self-test functionality may be distributed between separate device layers. Various beneficial transmitter circuitry layouts are disclosed.
