TRANSMITTER MODULE OUTPUTTING WAVELENGTH MULTIPLEXED LIGHT

摘要

A transmitter module having a plurality of semiconductor laser diodes (LDs) as optical signal sources that emit optical respective optical beams with specific wavelengths different from other is disclosed. The transmitter module includes, in addition to the LDs, a driver to drive LDs in the shunt-driving configuration. Inductors through which the bias currents for the LDs are provided are mounted on the driver as interposing a spacer and a top carrier.
