• Effect of etching mask and etching solution on V-groove formation in InP micromachining

    One of the most challenging tasks in photodetector packaging is to couple optical fiber to the detector. Because the size of detector and optical fiber is very small, accurate and accurate alignment is very important. Today, in most cases, this is achieved through time-consuming and costly active alignment technology, which involves individually adjusting each fiber while the diode is working to obtain maximum response and fixation. Therefore, it is necessary to develop passive self-aligning technology, which has less time consumption, lower cost, reliability, rationality and effectiveness. As we all know,…
