ABSTRACT
A ZnO/MgZnO-based one-dimensional photonic crystal multiquantum well laser operating at an emission wavelength of 360.7 nm is demonstrated. The photonic crystal providing optical feedback was fabricated in the form of parallel grooves with a period of 277.3 nm and a depth of 100 nm in a Si3N4 layer deposited directly on the epitaxial material. At a temperature of 11 K, 16 mW peak power is emitted from the laser surface, and the threshold intensity amounts to 0.33 MW/cm2. From temperature-dependent output power versus pump intensity curves, we deduced a T0 of 60 K and a maximal operating temperature of 135 K.
