摘要 | The invention is an optical apparatus and method of fabrication wherein an optical device such as a semiconductor laser includes a grating and a waveguide optically coupled to the grating. At least a portion of the waveguide coupled to the grating has a width which varies along the length of the waveguide in such a manner as to broaden the spectral line width of light output from the device. The width can be varied according to linear, sinusoidal or saw-tooth functions. A broadened line width permits pumping of a Raman amplifier at a high power without inducing any significant Brillouin Scattering. |
其他摘要 | 本发明是一种光学设备和制造方法,其中诸如半导体激光器的光学器件包括光栅和光学耦合到光栅的波导。耦合到光栅的波导的至少一部分具有沿波导长度变化的宽度,以便加宽从器件输出的光的谱线宽度。宽度可根据线性,正弦或锯齿功能而变化。加宽的线宽允许以高功率泵浦拉曼放大器,而不会引起任何明显的布里渊散射。 |
