Methods, systems, and apparatus, including an optical receiver including an optical source, including a substrate; a laser provided on the substrate, the laser having first and second sides and outputting first light from the first side and second light from the second side, the first light output from the first side of the laser has a first power and the second light output from the second side has a second power; and a first modulator that receives the first light and a second modulator that receives the second light, such that the power of the first light at an input of the first modulator is substantially equal to the power of the second light at an input of the second modulator.

Photonic integrated circuit

Methods, systems, and apparatus, including an optical receiver including a laser including a gain section; and a first tunable reflector configured to output a reference signal; a first coupler formed over the substrate; a shutter variable optical attenuator formed over the substrate, the shutter variable optical attenuator including an input port configured to receive the first portion of the reference signal from the laser; and an output port configured to provide or to block, based on a control signal, the first portion of the reference signal from the laser; and a second coupler including a first port configured to receive the first portion of the reference signal from the shutter variable optical attenuator; and a second port configured to (i) provide the first portion of the reference signal from the shutter variable optical attenuator to an optical analyzer or (ii) receive a data signal from a transmitter.
