Abstract: 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.

Abstract: This invention provides a light-emitting module in which the semiconductor light-emitting device and its driver circuit are arranged in side by side configuration, thereby realizing a high-speed transmission. The light-emitting module comprises the first beam splitter that splits light emitted from the front surface of the light-emitting device into an output light and a monitoring light. The monitored light is split again by the second splitter into the first and second monitoring light, one of which is monitored by the wavelength detector. Since the wavelength detector monitors the front light emitted from the light-emitting device, the driver can be arranged in side by side to the light-emitting device.
