| titleOfInvention | Laser Device with wavelength stabilizer |
| abstract | The present invention relates to a TO-type laser device capable of reducing the line width of a laser beam and transmitting the laser beam over a long distance. A laser device according to the present invention includes a laser diode chip (100) for emitting laser light; A wavelength selective filter; A collimating lens 200 installed on the optical path between the laser diode chip 100 and the wavelength selective filter to collimate the light emitted from the laser diode chip 100; A laser diode disposed on the optical path between the laser diode chip 100 and the wavelength selective filter for generating a laser beam traveling horizontally with respect to the bottom surface of the package, A partial reflection mirror 300; And a photodiode monitoring photodiode (500) disposed on the optical path through which the laser beam reflected from the wavelength selective filter after being emitted from the laser diode chip (100) passes through the 45 degree partial reflecting mirror (300) The temperature of the thermoelectric element to which the laser diode chip is attached is adjusted or the temperature of the etalon filter is adjusted to maintain the relationship between the laser light and the wavelength of the etalon filter constant, 0 "signal is further attenuated so that the line width of the laser signal is narrowed so that the high-speed modulated optical signal is transmitted to a longer distance. The object of the present invention is to obtain a laser signal capable of high-speed modulation and long-distance communication using a low-priced TO type package by arranging parts with a 45-degree partial reflection mirror as a center. Type package that allows high-speed modulated laser light to be transmitted to a long distance when the wavelength of the laser light is changed to a desired wavelength, and when the wavelength of the laser light is not adjusted, is provided . |
