| 摘要 |
An optical transmitting apparatus includes an optical filter, a port that monitor light transmitted through the optical filter, a port that monitor not light transmitted through the optical filter, an optical waveguide substrate on which the optical filter and an optical waveguide which includes a port that monitors the characteristic of the light which passes through the optical filter, a semiconductor laser and a heater that is capable of independently adjust the wavelength characteristic of any of the optical waveguide and the semiconductor laser, and the optical waveguide substrate and the semiconductor laser are integrated such that the temperature of the optical waveguide substrate and the semiconductor laser can be collectively adjusted. |
