Abstract

Single-mode high-power emission from a single VCSEL can be achieved by means of mode control in an external resonator. A problem arises how to analyse interference between wave field coming from external resonator to VCSEL structure. Analytical approach is formulated allowing for simplified description of the system. Numerical approach is based on 3-D bi-directional beam propagation method. Modal content and discrimination of higher-order modes in passive resonator are examined. Besides, above threshold operation of optical modes is simulated using multiple iterations. A method based on functions of Krylov's subspace, is developed to find a number of optical modes in a VCSEL with gain and index distributions established by the oscillating mode. In calculations, both Fourier and space variable descriptions of beam propagation are combined. This approach allows us to evaluate critical conditions for single-mode operation.
