| 简介 |
The inventive optical comb-spectrum luminescent source for photonic applications is designed in the form of a small-sized optical comb-spectrum source operating within a wavelength range of 1500-1600 nm for producing a spectral wavelength-division multiplexing effect in fiber-optic communications systems. The invention makes it possible to develop a small-sized and low-cost optical comb-spectrum source having a simple structural design. Comb-spectrum radiation is obtained by modulating the stimulated luminescence of rare-earth ions in a glass matrix by means of a Fabry-Perot resonator. The optical comb-spectrum luminescent source (1) comprises, located along the same optical axis, a pumping source (2), a focusing lens (3) and a light intensifier (4) in the form of an active solid-state cell (5) arranged inside the Fabry-Perot resonator. The active cell (5) is in the form of a plane-parallel luminescent plate made of a laser glass, the optical radiation axis of the pumping source being perpendicular to the plane of the Fabry-Perot resonator. The mirrors (6, 7) of the Fabry-Perot resonator can be applied directly to the planes of the plane-parallel luminescent plate. A highly-concentrated phosphate laser glass activated with ytterbium and erbium is used as an active medium. |
