摘要： The first and second optical waveguide device portions are optically coupled by 45-degree total reflection mirrors integrally formed in the respective device portions. The light generated by the first optical waveguide device portion is bent upward by the total reflection mirror of the first optical waveguide device portion. The light is totally reflected by the 45-degree total reflection mirror of the second optical waveguide device portion, and coupled to the second optical waveguide device portion. The first optical waveguide device portion has a lens device for focusing the emitted light onto a light emitting portion. The second optical waveguide device portion has a lens device for focusing the incident light onto a light receiving portion.

摘要： Included are: a gain chip having a gain unit and a phase control region; a current supply for causing a positive current to flow to the phase control region; a voltage supply for applying a bias voltage to the phase control region; and a control unit for selectively driving the current supply or the voltage supply depending on a direction of the wavelength shift. The control unit drives the current supply when a laser wavelength is to be shifted to a shorter wavelength side from a wavelength with the current supply and the voltage supply being turned off, and drives the voltage supply when the laser wavelength is to be shifted to a longer wavelength side from a wavelength with the current supply and the voltage supply being turned off.

摘要： A wavelength tunable filter and a wavelength tunable laser module are a codirectional coupler type whose characteristics do not vary significantly with a process error. They are structured so as to include a semiconductor substrate which has a first optical waveguide and a second optical waveguide. The first and the second optical waveguides are extended from a first side of the semiconductor substrate to an opposing second side thereof. The first optical waveguide includes a first core layer, which has a planar layout having periodic convexes and concaves, and a pair of electrodes, which vertically sandwich the first core layer. The second optical waveguide includes a second core layer, which has a lower refractive index than the first core layer. Further, a layer having the same composition and film thickness as the second core layer is placed under the first core layer.
