Abstract

In an embodiment, the invention provides a device for optical communications, such as an optical transceiver or optical transmitter, comprising: a photonic integrated circuit including first and second semiconductor laser sources (2, 3) having a first and a second nominal wavelengths, wherein the first and second semiconductor laser sources are wavelength tunable, anda thermal unit (7) thermally coupled to the first and second semiconductor laser sources to impose a shared temperature on the first and second semiconductor laser sources, so that the first and second semiconductor laser sources transmit a first and a second optical signals (12, 13) at a first and a second transmission wavelengths, wherein the first and second transmission wavelengths are identically shifted from the first and second nominal wavelengths as a function of the shared temperature. The device may further comprise a temperature controller (5) for controlling the thermal unit and a sensor (6) for sensing the shared temperature.
