This Small Business Innovation Research (SBIR) Phase I project is a feasibility study on electrically tunable lasers made from novel liquid crystal based tunable photonic crystals (TPC). As predicted by a theoretical model and experiment results, the tuning of the laser wavelength is realized via tuning the TPC stop band. When doped with lasing dye(s) and pumped by a pumping laser, electrically tunable lasing is expected over a wide spectral range of 200 nm. The lasers are also expected to have greater than 20% light-to-light efficiency in a robust, lightweight, compact, and low cost package. The Phase I effort is devoted to developing tunable lasers followed by performance improvement by researching the lasing action and the sources affecting the lasing performance. In addition, the feasibility of using other pumping sources will be explored.
