Abstract
A novel scheme of tunable folded Solc filter is proposed using Total Internal Reflection (TIR) in a 50 mm long, 1000 μm thick, bulk single crystal trapezoidal slab of LiNbO3. Fresnel phase shift for each TIR and propagation phase shift between two successive TIR points have been utilized for finding required polarization rotation by Jones calculus for folded solc action. Analytical expressions for central wavelength and bandwidth for transmission maxima have been formulated. Results indicate a narrow 3 dB bandwidth of 0.8 nm for transmission bands having transmission maxima around 1550 nm for the proposed slab with a temperature tunable rate approximately 0.008 nm/°C.
