Summary:To provide a VCSEL where the basic mode is stable.SOLUTION: A VCSEL 200 can include an active region 240 (for example, one or more quantum wells) and a chirp pattern reflector 250. The active region is composed to be electrically pumped, and the active region is generated with light in which the activity region has a basic mode and higher mode. The chirp pattern reflector can include a first portion presented in the active region as a first portion of the effective mirror with a concave type, and a second portion presented in the active region as a second portion of the effective mirror having a convex shape.SELECTED DRAWING: Figure 2 【課題】基本モードが安定な垂直共振器面発光レーザ（ＶＣＳＥＬ）を提供する。【解決手段】垂直共振器面発光レーザ（ＶＣＳＥＬ）２００は、活性領域（例えば、１つ以上の量子井戸）２４０及びチャープパターン反射器２５０を含み得る。活性領域は、電気的にポンピングされるように構成され得、活性領域が基本モード及び高次モードを有する光を生成する。チャープパターン反射器は、凹形状を有する有効ミラーの第１の部分として活性領域に提示する第１の部分と、凸形状を有する有効ミラーの第２の部分として活性領域に提示する第２の部分とを含み得る。【選択図】図２
