摘要： An optical gain medium, and a method for forming the same, is provided that exhibits lower wavelength crosstalk when configured as an optical amplifier than prior art optical gain media. The optical gain medium of the present invention includes a buried heterostructure waveguide fabricated in a multiple quantum well (MQW) region. The MQW region in which the buried heterostructure waveguide is located exhibits a continuously changing bandgap as a function of position along the waveguide direction, preferably such that the gain provided by the optical gain medium changes exponentially as a function of position along the waveguide direction. In a preferred embodiment, the MQW region in which the buried heterostructure waveguide is buried is grown using a selective-area-growth (SAG) technique, and is made up of at least two quantum wells, with at least one of the quantum wells having a size and composition that vary as a function of position along the waveguide direction.

摘要： A semiconductor laser device has a quantum well active layer including a well layer and a barrier layer laminated on a semiconductor substrate. The quantum well active layer contains II group atoms such as Zn atoms. The quantum well active layer is so formed that a bandgap of the quantum well active layer in the vicinity of an end surface of a laser resonator is larger than a bandgap of the quantum well active layer inside the laser resonator. The II group atoms contained in the quantum well active layer inside the laser resonator make up for vacancies introduced therein so as to inhibit fluctuation of the bandgap of the quantum well active layer inside the laser resonator and thereby to enhance long-term reliability of the semiconductor laser device.

摘要： A semiconductor optical functional device is divided into two regions of a first region 1 and a second region 2 adjacent to each other in a longitudinal direction of a semiconductor optical waveguide. The first region 1 is provided with a region including an MQW structure in which a compressive strain is introduced, and the second region 2 is provided with a region including an MQW structure in which a tensile strain is introduced. Electrodes 3 and 4 formed separately and independently from each other are respectively disposed on the first region 1 and the second region 2, and bias voltages applied to the electrodes 3 and 4 are adjusted so that transmissivities for light having a TE mode component and light having a TM mode component are independently controlled.

摘要： The broadband semiconductor optical amplifier fabricated in accordance with the teachings of the present invention comprises first and second active semiconductor regions (50, 51) disposed in tandem with each other, and means for injecting current (I.sub.1,I.sub.2) into the first and second active semiconductor regions to provide gain distributions over wavelength regions in the two active semiconductor regions which partially overlap to form a combined gain distribution over a wider range of wavelengths. Anti-reflection coatings (54, 55) are disposed on the extreme ends of the combined structure. Tuneable wavelength selective amplification over the wider range is achieved in various embodiments by including a tunable optical bandpass filter (53) or by including various tunable auxiliary light guiding structures (115, 116; 140; or 450) to which and from which light power is coupled from and to the active semiconductor regions of the amplifier, respectively.
