Hybrid coupling in integrated injection laser arrays
A. Yu. Mikhal'kov, A. G. Plyavenek
Abstract:
Analytic and numerical investigations are reported of the mode composition of the radiation emitted by integrated injection laser arrays consisting of an arbitrary number of components coupled by Y junctions and by a slight overlap of the fields of parallel parts of waveguides. An analysis of symmetric Y couplers is made also near the lasing threshold. A strong dependence of the mode composition of the output radiation on the weak coupling between the parallel waveguides and/or on the waveguide length is revealed. An allowance for weak coupling in Y-coupler arrays alters considerably the distribution of the radiation intensity of the first array mode in the far-field zone and the changes are manifested mainly by a relative increase of the side lobes of the angular distribution of the output radiation.
