Embodiment Construction
[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0013] Such as figure 1 As shown, the longitudinal structure of the low divergence angle full Bragg reflective waveguide semiconductor laser array of the present invention is as follows from bottom to top: N-type substrate 101, N-type confinement layer 102, N-type Bragg reflective waveguide 103, active region 104, P-type Bragg reflection waveguide 105 , P-type confinement layer 106 , and P-type capping layer 107 . Among them, the N-type Bragg reflective waveguide 103 is composed of n (n≥1) pairs of high and low refractive index materials periodically arranged, and each period includes an N-type high-refractive-index layer 108 and an N-type low-refractive-index layer 109; a P-type Bragg The reflective waveguide 105 is composed of m (m≥1) pairs of high and low refractive index materials periodically arranged, and each period includes a...
