摘要： An optical module includes a light-emitting device that outputs laser light, a temperature detection unit that is arranged in proximity to the light-emitting device and detects the temperature of the light-emitting device, a wavelength monitor unit that receives laser light outputted from the light-emitting device and having passed through an optical filter and monitors the wavelength of the laser light, and a temperature adjustment unit that adjusts the wavelength of laser light outputted from the light-emitting device based on a signal outputted from the wavelength monitor unit. The temperature adjustment unit adjusts the wavelength of the laser light so as to fall within a wavelength range, in which the wavelength is adjustable by the wavelength monitor unit, based on a signal from the temperature detection unit, and then adjusts the wavelength of the laser light so as to be locked at a predetermined wavelength based on the signal from the wavelength monitor unit. The signal from the temperature detection unit is used to correct lock wavelength shift caused by the temperature characteristic of the optical filter by estimating the temperature of the optical filter based on the temperature of the light-emitting device.

摘要： A wavelength monitor capable of obtaining an optical detection signal of high quality is proposed. In the wavelength monitor, a light incident surface of an optical filter is disposed with an inclination relative to the light incident direction. With this arrangement, it is possible to make the route of a reflection light that has been reflected from the light incident surface of the optical filter deviate large from the route of an incident light that has been incident to the optical filter. Consequently, the reflected light is prevented from being incident to a semiconductor laser device or optical detectors.
