Abstract :
It is shown that 2D lattice gratings, despite being placed outside the waveguide region, exhibit sufficiently strong coupling coefficients that optical modes rapidly. couple transversely into the etched grating region, yielding high coupling coefficients of 270 cm/sup -1/. This performance allows mode-hop-free lasing operation in DBR structures.
