摘要	A monolithic single-mode semiconductor laser comprises three coupled Fabry-Perot cavities in tandem, each separated by a vertically etched air gap of a size that is substantially equal to an odd-integer multiple of quarter-wavelength. The middle cavity is actively pumped to provide gains to the combined cavity laser. The other cavities are substantially transparent and act as an optical filter to select one of the longitudinal modes of the middle cavity as the lasing mode. The lengths of the two passive cavities are substantially different so that a narrow filtering function with a large free spectral range is obtained for optimal mode selectivity.
其他摘要	单片单模半导体激光器包括串联的三个耦合的法布里 - 珀罗腔，每个腔由垂直蚀刻的气隙隔开，该气隙的尺寸基本上等于四分之一波长的奇数倍。中间腔被主动泵浦以为组合腔激光器提供增益。其他腔体基本上是透明的并且用作光学滤波器以选择中间腔体的纵向模式之一作为激光模式。两个被动腔的长度基本上不同，从而获得具有大的自由光谱范围的窄滤波函数，以获得最佳模式选择性。
主权项	A semiconductor laser comprising: an active optical cavity having two partially reflecting elements and an active waveguide, said active waveguide being sandwiched between a pair of electrodes for injecting current to provide optical gain, a first passive optical etalon filter having two partially reflecting elements, said first passive optical etalon filter being coupled with the active optical cavity through a common partially reflecting element, a second passive optical etalon filter having two partially reflecting elements, said second passive optical etalon filter being coupled with the active optical cavity through a common partially reflecting element, wherein the first and the second passive optical etalon filters act as wavelength-selective reflectors to select one of the longitudinal modes of the active optical cavity as the lasing mode.
