Deep learning is used to segment ophthalmic OCT images in order to recognize the tear meniscus of the human eye.

New fiber technology is poised to deliver multikilowatt power, ultrashort pulse durations, repetition rates up to 1 GHz, and high beam quality in a small package.

Collinear laser excitation and Raman scattering collection enables measurement of samples inside of packaging to increase field safety.

Exploiting the infinite number of polarization states of unpolarized thermal light and their correlation properties leads to a new approach for secure data communications.

Instead of depending on fixed-position fiber Bragg gratings, core-launched laser light can couple to the cladding modes of standard fiber through Brillouin dynamic gratings and...
