摘要： The object of the present invention is to provide an optical module for a WDM communication system, in which the oscillation wavelength is on the grid of the WDM regulation. The optical output power and the oscillation wavelength can be controlled independently. The present module includes a semiconductor light-emitting device, a wedge shaped etalon device and two light-receiving devices. The etalon contains a second portion, on which anti-reflection films are coated, and a first portion. One of the receiving devices detects light transmitted through the second portion of the etalon, while the other device detects light through the first portion. A signal from the former device controls the output power of the light-emitting device, while a signal from the latter receiving device controls the oscillation wavelength of the laser.

摘要： The light-emitting module includes a semiconductor light-emitting device, a first optical detector for monitoring the magnitude of light emitted from the semiconductor device, a second optical detector for monitoring an oscillation wavelength of the semiconductor device, and an Etalon. The first detector is located in a position where the wavelength variation of the transmitted light from the Etalon is relatively small, while the second detector is located in a position where the wavelength variation of the transmitted light is relatively large. The geometrical size of the second detector along the first direction is wider than that along the second direction normal to the first direction; this thus enhances the efficiency of wavelength sensitivity.
