摘要	A VCSEL waveguide grating coupler is provided such that a first and second mirror are positioned to define a resonant cavity between them. The waveguide grating coupler further includes a waveguide having a first grating formed as a part of the waveguide to couple light of a first polarization mode into the waveguide. A second grating is formed on the waveguide grating coupler and is orthogonal to the first grating. The second grating is operative to enhance the light coupled to the waveguide by creating a loss difference between light of the first polarization mode and light of a second polarization mode, so that light of the first polarization mode lases preferentially within the VCSEL.
其他摘要	提供VCSEL波导光栅耦合器，使得第一和第二反射镜定位成在它们之间限定谐振腔。波导光栅耦合器还包括波导，该波导具有形成为波导的一部分的第一光栅，以将第一偏振模式的光耦合到波导中。第二光栅形成在波导光栅耦合器上并与第一光栅正交。第二光栅可操作以通过在第一偏振模式的光和第二偏振模式的光之间产生损耗差来增强耦合到波导的光，使得第一偏振模式的光优先在VCSEL内发光。
主权项	A waveguide grating coupler comprising: first and second mirrors positioned to define a resonant cavity between said first and second mirrors; a waveguide; a first grating formed as a part of said waveguide to couple light of a first polarization mode into the waveguide; and a second grating, wherein said second grating is orthogonal to the first grating, and wherein said second grating enhances the light coupled to said waveguide by reducing light of a second polarization mode different from the first polarization mode within said resonant cavity, such that light within said resonant cavity lases preferentially in said first polarization mode.
