摘要:
An optical module of the present invention can stabilize e.g. the temperature of a wavelength monitor portion so that the oscillating wavelength of a laser diode is stabilized. The laser diode and the wavelength monitor portion for monitoring the wavelength of the laser diode are included in a package, and are mounted onto a thermo module. The wavelength monitor portion comprise at least an optical filter positioned to receive and filter at least a component of the laser beam and a light receiving device to receive the filtered light through the optical filter and monitor a wavelength of the laser beam. A heat shield member for reducing heat transmission from the package to the wavelength monitor portion is arranged in at least one portion of a peripheral area of the wavelength monitor portion.
