The dependence of mode discrimination of TE<sub>00<\/sub> and TE<sub>01<\/sub> lateral modes on such laser crystal parameters as the mesa-stripe width, the mesa-groove depth, and the DBR depth is analysed. An algorithm is presented for choosing the value of these parameters depending on the required generation spectrum width for a given heterostructure design. The possibility of increasing the width of the emitting aperture while maintaining the single-mode generation regime is demonstrated, while the selection of lateral modes in narrow mesa-stripe waveguides is achieved due to different DBR reflection coefficients for TE<sub>00<\/sub> and TE<sub>01<\/sub> modes at a given DBR length. The resulting mesa-stripe broadening can be used to increase the optical power of a single-mode laser.<\/div>\n<div><\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> single-mode diode lasers, distributed Bragg reflector, lateral waveguide, mode selection, heterostructure.<\/div>\n<div><\/div>\n<div><b>Received:<\/b> 23.06.2022<\/div>\n","protected":false},"excerpt":{"rendered":"<p>V.
