FULLY OPTICAL MULTILAYER HETEROSTRUCTURE-BASED LASER RADIATION MODULATOR (VERSIONS) Russian patent published in 2013 - IPC G02F1/17 G02F1/19 

FIELD: physics.

SUBSTANCE: fully optical multilayer heterostructure-based laser radiation modulator has a substrate with a grown periodic multilayer heterostructure which is such that, change in the refraction index under the effect of exciting laser radiation in the active nonlinear semiconductor component of the heterostructure due to generation of dense electron-hole plasma causes change in intensity of the modulated incident radiation. The substrate has an optical window. The central layer of the active component of the periodic multilayer heterostructure has double the thickness of other layers of the active component of the heterostructure. The active nonlinear component of the multilayer heterostructure is selected from a group of semiconductor compounds A^IIB^VI or A^IIIB^V.

EFFECT: higher efficiency and operating speed of the modulator.
