Chapter 5 The Optical Directional Coupler

The directional coupler forms one of the building blocks of integrated quantum photonic devices and in optical telecommunication and sensing. These include power dividers, optical switches, optical

Low-Loss Silicon Directional Coupler with Arbitrary Coupling Ratios for

2 × 2 splitter meeting the essential requirements of broadband coupling, support for arbitrary coupling ratio, ultra low-loss, high fabrication tolerance, and a compact footprint. This is achieved based on a

Integrated dual-mode 3‹사dB power coupler based on tapered directional

In this paper, we pro-pose and demonstrate an on chip dual-mode 3 dB power coupler based on asymmetrical tapered two-waveguide structure.

Optical Directional Couplers | Springer Nature Link

The optical directional coupler, analogous to the microwave element 1 of the same name, consists of parallel channel optical waveguides sufficiently closely spaced that energy is transferred from one to

Microsoft Word

Here, by exploiting an asymmetric directional coupler design, we demonstrate non-volatile PCM-clad silicon photonic 1 × 2 and 2 × 2 switches with a low insertion loss of ~1 dB and a compact coupling

Optical Coupler

The optical couplers are recognized either as optical taps (1 × 2) couplers or directional (2 × 2) couplers. Depending on purpose, the power coupler splitting ratio can be different, with typical values being

Directional Couplers

Whether you need a directional coupler with 50-Ohm or 75-Ohm matching, DC passing or DC blocking, coaxial connectorized or surface mount case styles,
