Behind The Curtain: Developing The First Laser Based On Bound States In The Continuum (BIC)
By Marissa Stonefield

Nearly 90 years after it was predicted that certain wave states are able to remain perfectly confined, or bound, in an open system, this wave physics phenomenon — called bound states in the continuum (BIC) — has been demonstrated by researchers at UCSD in the form of the world’s first BIC laser. This Q&A discusses the design process and features of this lasing technology, as well as future steps in making BIC lasers electrically powered and how long it might take to build a BIC laser to custom specifications.

Theory And Measurement Of The Modulation Transfer Function (MTF)
By Image Science Ltd.

A modulation transfer function (MTF) is a quantitative and objective measure of the quality of an image formed by a lens or and electro-optical system. MTF is appropriate for lenses of all qualities and can be calculated from lens design data, which enables theoretical and actual performances to be compared. 

What Is InGaAs?
