  • Light source redundancy in optical communication devices
    Patent number: 10812181
    Abstract: An embodiment includes an optical transmitter. An optical transmitter may include a primary laser for transmitting a primary optical signal and a backup laser for transmitting a backup optical signal. The optical transmitter may further include a photonic integrated circuit (PIC). The PIC may include at least one input port configured to receive the primary optical signal from the primary laser and the backup optical signal from the backup laser. The PIC may also include at least one output port configured to receive each of the primary optical signal and the backup optical signal. The optical transmitter may be configured to activate the backup laser upon determining that the primary laser has failed or is failing.
