【摘要】 利用一种改进的液相外延技术进行了ＧａＡｓ衬底上ＩｎＧａＡｓＰ材料的生长，１０Ｋ温度下光荧光半宽度（ＦＷＨＭ）为１４ｍｅＶ，获得了阈值电流密度为３００Ａ／ｃｍ２的ＳＣＨ多层结构外延片，宽台面激光器最大连续输出功率达到２．１Ｗ。更多还原

【Abstract】 A modified liquid phase epitaxy method was used to grow InGaAsP materials on the GaAs substrate. The FWHM of photoluminescence at 10 K was 14 meV, wafers of SCH multilayer epitaxial structures were obtained with a threshold current density of 300 A/cm 2, and the hgihest CW output power obtained from wide stripe lasers was 2.1 W.更多还原
