Abstract
(EN)
This optical module comprises: a laser element; a wavelength detector; a modulator; a modulator driver; a coherent mixer that processes an input signal light inputted from outside, and generates a processing signal light; a photoelectric element that converts the processing signal light into a current signal; a transimpedance amplifier that converts the current signal into a voltage signal; and a housing inside which the laser element, the wavelength detector, the modulator, the modulator driver, the coherent mixer, the photoelectric element, and the transimpedance amplifier are mounted and sealed in an airtight manner, the housing having an optical output unit that outputs an output signal light, and an optical input unit into which the input signal light is inputted, the size of the housing in a width direction perpendicular to a length direction being 15 mm or less, and the laser element being disposed so as to output laser light in a direction opposite the side of the housing on which the optical output unit is provided.
