FBG Fiber Loop Mirror Sensor Design Basics

Fiber loop mirror configurations have been used in several different applications. One important application is sensing. Inserting a Fiber Bragg Grating (FBG) in the fiber loop mirror allows exploiting the switching feature of the loop mirror to enable enhanced sensing and accessing capabilities.

Polarization Splitter with Holey Fiber using OptiMode

Elliptical-hole core circular-hole holey fibers (EC-CHFs) can be engineered to provide absolutely single polarization transmission.

Nano Photonic Imager

Signal Quality Ratios

When designing or analyzing the performance of an analog or digital link, the following signal metrics are commonly used…

Optical Receiver Analysis (PIN-TIA-LA)

The overall performance of a point-to-point optical communication link is normally defined based on the minimum average optical power, measured at the input to the optical receiver…

Matched Filter Analysis

A matched filter is an ideal filter which acts upon a received signal so as to maximize its signal to noise ratio (SNR). Under conditions of additive white Gaussian noise, the SNR…

Digital Modulation Analysis (PSK)

Digital modulation systems are used to transmit digital (quantized) information over a medium such as air or optical fiber. Transmission is achieved by mapping the information…
