Abstract
Amplified spontaneous emission (ASE) in an organic-dye- (DCM-) doped poly(methyl methacrylate)/silica-gel hybrid material planar waveguide was investigated. ASE wavelength control and tuning in a wedge waveguide were realized. The tuning range of the waveguide can reach as much as 30 nm. This method can be applied to wide-range wavelength tuning in solid-state tunable lasers.
