TLDR
In this article, a low-loss and high-repeatability 4 × 4 optical matrix switch fabricated by using rhombic glass-block switch elements was described, and the maximum loss was 1.3 dB and the crosstalk was less than −55 dB, with a switching delay of less than 18 ms.Abstract:

Switching characteristics of laser diode switch
TL;DR: In this article, the authors studied the switching characteristics for laser diode switches controlled by the forward injection current and found that the turn-on response time is determined mainly by the space charge capacitance and was seen typically to be ten times the carrier lifetime.
