An acousto-optic tapped delay-line finite-impulse-response filter that operates at a system
intermediate frequency without requiring a reference optical beam is introduced. Principles …

We propose and demonstrate an optical system that performs adaptive notch filtering for RF
signals, where narrowband interference noise is rejected without knowing a priori its …

Photorefractive and photochromic effects are investigated in undoped semi-insulating GaP
at high temperature. The photochromic effect takes place at the temperature above 340 K …
