Research abstract
The elimination or suppression of filaments through the use of photonic crystal structures is proposed in this STTR. Filament formation is a well-known problem in high-power, broad area semiconductor diode lasers, often leading to catastrophic failure of the diodes. The diode failure also normally results in a system failure in the systems in which the diodes are employed. By using a bi-directional periodic structure, milled into the laser using a Focused Ion Beam, it is shown that mode control can be exercised over the optical mode of the high-power, broad area diode laser. Mode control serves to eliminate or suppress filament formation in the diode laser, thereby eliminating or suppressing this pernicious failure mode.
