摘要： There is provided a phase control portion for controlling phase of a laser beam resonated in a resonator based on detected results by two optical detectors. The phase control portion adjusts the longitudinal mode positions by a feedback control so that a ratio of intensities detected by the two optical detectors comes to a predetermined reference value. To one of the optical detectors, part of a laser beam outputted from the resonator is irradiated as it is, whereas, to the other one of the optical detectors, part of the laser beam outputted from the resonator is irradiated after passing through an etalon. An FSR of the etalon is a double of that of another etalon in the resonator.

摘要： A wavelength selection filter, a wavelenth selection laser, and a tunable laser for suppressing adverse effects of non-selected light when selected light is obtained by the wavelength selection filter. A linear polarizer is arranged on a side of the wavelength selection filter from which incoming light enters, and a first faraday element and a second faraday element arranged at respective locations between the linear polarizer and the wavelength selection filter, and between the wavelength selection filter and a reflection mirror for reflecting light having passed through the wavelength selection filter. After incoming light passes through a linear polarizer, selected light passes through the wavelength selection filter and is reflected by the reflection mirror, while non-selected light is reflected by the wavelength selection filter. The selected light and the non-selected light differ in the number of times they pass through faraday elements before they return to the linear polarizer.

摘要： A tapered waveguide is provided for connection between an input waveguide and a photodiode. The width of the tapered waveguide increases as it extends from the input end that is connected to the input waveguide towards the output end that is connected to the photodiode. The tapered waveguide has an optimum half spread angle to cause higher-order mode excitation when receiving optical signal from the input waveguide. The photodiode either has a constant width or increases in width as it extends away from the output end of the tapered waveguide, its half spread angle being equal to or less than the half spread angle of the tapered waveguide.
