摘要: A waveguide ( 10 ) is provided having a two-dimensional optical wavelength Bragg grating 20 embedded within semiconductor laser medium 16 ). More particularly, the includes an active region sandwiched between n-doped and p-doped cladding layers 14, 22 The formed in Upper lower electrodes 24, 26 are defined on opposite sides of to complete structure provides simultaneous frequency selective feedback for mode control both longitudinal lateral directions.
