摘要 | PURPOSE:To obtain a self-pulsating LD characterized by excellent stability and reproducibility, by forming a saturable absorbing region comprising a multiplex quantum well structure of a semiconductor as a unitary body together with the LD. CONSTITUTION:On an N-type GaAs substrate 103, an N-type GaAs buffer layer 104, an N-type Al0.4Ga0.6As clad layer 105, a non-doped Al0.05Ga0.95As active layer 106, a P-type Al0.4Ga0.6As clad layer 107 and a P-type GaAs cap layer 108 are formed by an MO-CVD method. A stripe shaped SiO2 mask is attached on the cap layer 108, and a part other than the stripe part is removed to the substrate 103 by chemical etching. A P-type Al0.4Ga0.6As layer 109 and an N- type Al0.4Ga0.6As layer 110 are grown in embedded manner by the MO-CVD method. After the substrate 103 is lapped to a suitable thickness, electrodes 111 and 111' are evaporated. Then cleavage is formed. On the cleaved plane, which is vertical to the direction of a resonator, a non-doped GaAs layers 112 and non-doped Al0.4Ga0.6As layer 113 are grown. Either of the layers 112 and the layers 113 have 50 layers. A saturable absorbing region 102 is manufactured. |
其他摘要 | 目的:通过与LD一起形成包括半导体的多重量子阱结构作为整体的可饱和吸收区,获得具有优异稳定性和再现性的自脉冲LD。组成:在N型GaAs衬底103上,N型GaAs缓冲层104,N型Al0.4Ga0.6As包层105,非掺杂Al0.05Ga0.95As有源层106,P型通过MO-CVD法形成Al0.4Ga0.6As包层107和P型GaAs盖层108。条形SiO 2掩模附着在盖层108上,并且通过化学蚀刻将除条形部分之外的部分去除到基板103。通过MO-CVD方法以嵌入方式生长P型Al0.4Ga0.6As层109和N-型Al0.4Ga0.6As层110。在将衬底103研磨至合适的厚度之后,蒸发电极111和111'。然后形成切割。在垂直于谐振器方向的解理面上,生长非掺杂的GaAs层112和未掺杂的Al0.4Ga0.6As层113。层112和层113中的任一层具有50层。制造可饱和吸收区域102。 |
