MONOLITHIC SIGNAL COUPLER FOR HIGH-ASPECT RATIO SOLID-STATE GAIN MEDIA |
摘要 |
A coupler and method of coupling a signal beam between from a circular-core fiber to a rectangular-core cross section fiber includes providing an optical coupler having an optical core with a high-aspect ratio cross section at one end and a circular cross section at an opposite end to receive a signal beam having a circular cross section. The signal beam is propagated from the circular fiber to the rectangular-core cross section fiber in a narrow, fast-axis direction while maintaining the size and divergence of the signal beam as it propagates. The signal beam is expanded in size while producing a collimated beam from the circular cross section end to the rectangular-core cross section end in a wide, slow-axis direction. |
