摘要： A voltage-controllable output coupler for a laser, comprising: a liquid crystal cell that provides a change in birefringence in response to an applied voltage; and a polariser oriented with respect to the liquid crystal cell to collectively form a variable reflectance mirror for the laser; wherein output coupling of the laser is controllable by applying voltage to the liquid crystal cell for a switching interval to switch the variable reflectance mirror from high reflectance to low reflectance, and vice versa, thus actively Q-switching or cavity dumping the laser.

摘要： The present invention relates generally to a photodiode and, in particular, to operating a photodiode in a zero-mode operation, where the photodiode operates at either zero current or zero voltage. Accordingly, there is provided a circuit configured for detecting light, including a photodiode; and a circuit configured for operating the photodiode at zero-mode.
