摘要	PURPOSE:To obtain a gain spectrum area wherein there is no gain difference with wavelength by providing a wavelength selective loss means which eliminates light with a specific wavelength or wavelength by demultiplexing or absorbing the light from an optical amplification area in waveguide structure for amplifying waveguide light. CONSTITUTION:The wavelength selective loss means consists of a main waveguide connected directly to the optical amplification area 19, an adjacent sub waveguide, a grating which couples those waveguides on a wavelength selective basis, a directional coupler, etc. A part which becomes an optical input/output part is removed by wet etching almost to an optical waveguide 6, a p type electrode 13 is provided on the top surface of a cap layer 8 and at a part which is formed into the optical amplification area 19, and an n type electrode 14 is provided on the reverse surface of a substrate Then the surface which becomes the optical input/output part is cut by cleavage and a ZrO2 film is vapor-deposited on its end surface to form a nonreflective coating film 15. Consequently, the optical amplifier which is improved in gain spectrum and has no difference in gain with wavelength is obtained.
其他摘要	目的：通过提供波长选择性损耗装置，通过多路分解或吸收来自波导结构中光放大区域的光来消除具有特定波长或波长的光，以获得增益光谱区域，其中波长没有增益差异，用于放大波导光。组成：波长选择性损耗装置包括一个直接连接到光放大区域19的主波导，一个相邻的子波导，一个在波长选择的基础上耦合这些波导的光栅，一个定向耦合器等。一个成为光学的部分输入/输出部分通过湿蚀刻几乎移除到光波导6，p型电极13设置在盖层8的顶表面上和形成光放大区域19的部分，和n型电极然后，通过解理切割成为光输入/输出部分的表面，并在其端面上气相沉积ZrO 2膜，以形成非反射涂膜15。获得了增益谱得到改善并且增益与波长无差异的光放大器。
