Home / Customization Process for Low-Temperature Resistant Fiber Optic Couplers for Local Area Networks
In this paper, we propose and design a reconfigurable fiber-to-waveguide coupling (RFWC) module based on a PCM overlaid switchable directional coupler (SDC), which serves both
Temperature changes cause a shift in wavelength and coupling length increase which describes the characteristics of the thermo-optic effects on the directional couplers.
Fiber couplers are fiber devices for coupling light from one or several input fibers to one or several output fibers, or from free space into a fiber.
Three fabrication methods are employed: fusion, micro-optics, and planar lightwave circuit (PLC), each optimized for specific performance and cost requirements.
