摘要： The present invention provides a short resonator laser capable of high-speed operation with a low threshold value current and an element structure realizing a wavelength changeable laser having an excellent wavelength stability. A laser resonator waveguide is formed in such a manner that its lateral width is set to a wide value allowing lateral-multi mode at a part or the entire portion of the waveguide. This enables enhancement of a laser gain and reduction of electric resistance and thermal resistance while keeping the aforementioned characteristics of the short resonator laser. Here, by using self-focusing effect as a result of multi-mode interference effect, it is possible to reduce the mode conversion loss in the laser resonator and the light intensity distribution at the laser emitting end becomes a single-hill lowest order mode. Thus, it is possible to obtain a structure appropriate for connection with an optical fiber.
摘要翻译：本发明提供一种具有低阈值电流的高速操作的短谐振器激光器和实现具有优异的波长稳定性的波长可变激光器的元件结构。激光谐振器波导以这样的方式形成，使得其横向宽度被设定为允许波导的一部分或全部部分处的横向多模式的宽值。这使得能够在保持上述短谐振器激光器的特性的同时增强激光增益和降低电阻和热阻。这里，作为多模式干涉效应的结果，通过使用自聚焦效果，可以降低激光谐振器的模式转换损耗，并且激光发射端的光强度分布变为单峰最低阶模式。因此，可以获得适合于与光纤连接的结构。

摘要： In order to form a wavelength tunable laser capable of tuning a wave over a wide range by simple control means, a thin film heater is mounted either over an upper electrode of a ridge waveguide semiconductor laser having ridge waveguides on a semiconductor substrate or over the semiconductor substrate and on both sides of the ridge waveguide with a gap of a few &mgr;m. By controlling a current passed to the thin film heater, the oscillation wavelength of the semiconductor laser is tuned. In the case where the thin film heater is mounted over an upper electrode of a ridge waveguide, a nonconductor is formed on both sides of the ridge conductor to more efficiently enable heat from the heater to reach an active layer of the ridge waveguide more efficiently.
