Photo-thermo-refractive (PTR) glass is a photosensitive multi-component silicate matrix incorporating halides and metal dopants. Upon exposure to ultraviolet or ultrafast laser light and subsequent ...

In physics, as in life, it's always good to look at things from different perspectives. Since the beginning of quantum physics, how light moves and interacts with matter around it has mostly been ...

This review analyzes III-V monolithic integrated tunable lasers, highlighting design principles, performance trade-offs, and ...

The wavefront of the emerging beam carries refractive information relating to the eye’s optics. For example, if the eye is emmetropic (i.e., the eye’s optics are without refractive error), the ...
