Efficient optical waveguide coupler

Applied Optics, 1980
A new method for high-efficiency interconnection of two planar optical waveguides is described. This technique is based on mode-matched coupling and is particularly useful when the difference between the refractive indices of the individual guides is large.

Spectrally Efficient Optical Communications

Asia Communications and Photonics Conference 2015, 2015
The paper reviews most diffuse techniques used for increasing spectral efficiency in optical communication, considering different network segments. Time-frequency packing will be described, and compared to Nyquist wavelength-division multiplexing and orthogonal frequency-division multiplexing.

Efficient broadband composite optical isolator

Applied Optics, 2013
A new design of a broadband optical isolator, composed as a sequence of ordinary Faraday rotators and achromatic quarter-wave plates (QWPs), is presented. In particular, we demonstrate that by using four Faraday rotators and six achromatic QWPs, rotated at specific angles, optical isolation better than 15 dB over the range from 700 to 1000 nm can be ...
