(6+1)x1 Side Pump Combiner

(6+1)x1 side pump combiners have low loss and high pump efficiency. Due to the nature of side coupling, it can maintain beam quality, and has better resistance to back reflections. It is good for intra-cavity pump schemes, ideal for reverse pumping, and perfect for bi-directional single cavity and single mode designs. Features High Isolation to […]

Polarization Diversity Receiver

Ideal for Fiber Optic Interferometers Lightel’s Polarization Diversity Receiver (PDR) performs as a receiver for fiber optic interferometers that are susceptible to polarization fading because of random birefringence variations. The device incorporates three independent polarized PIN diodes ensuring that at least one output has high interferometric visibility. This approach eliminates polarization fading in fiber optic
