2D-lattice distributed reflector laser

Summary form only given.Currently, there is much interest in low cost techniques for achieving simple, robust laser sources with high quality spectral performance for data-communication applications. Particular interest currently exists in the construction of DFB and DBR lasers without using expensive regrowth techniques. Here, deep etching of DBRs has produced encouraging results. In this paper, however, we report for the first time the successful construction and operation of a two-dimensional (2D)-lattice InGaAsP-InP distributed reflector laser. The photonic-type lattice grating structure is introduced into a standard Fabry-Perot diode laser by postprocessing using focused ion beam etching (FIBE).
