Simple description of laterally resonant, distributed‐feedback‐like modes of arrays of antiguides
TLDR
Laterally resonant modes of infinite arrays were described for the first time in this paper, where the Bloch-function method was used to provide a simple, yet accurate treatment of the leaky modes of finite-extent antiguided arrays.Abstract:
The Bloch‐function method is used to provide a simple, yet accurate treatment of the leaky modes of infinite‐extent antiguided arrays. Laterally resonant modes of infinite arrays are described for the first time. Bloch‐function solutions for infinite arrays are used to explain key characteristics of the modes of finite‐extent antiguided arrays. It is found that the resonant modes of antiguided arrays satisfy the second‐order lateral Bragg condition, and consequently are analogous to the modes of second‐order distributed‐feedback (DFB) lasers. In effect, the resonant‐optical‐waveguide (ROW) array is a second‐order lateral DFB structure with the radiative component along the longitudinal device axis, and zero stopband.read more

High-power monolithic phase-locked arrays of antiguided semiconductor diode lasers
TL;DR: In this paper, it was shown that when gain is placed in the low-index regions of large arrays (≥10 elements), the array mode favored to lase is the leaky mode (inphase or out-of-phase) closest to its respective resonance.

Coupled‐mode analysis of phase‐locked injection laser arrays
TL;DR: In this article, a coupledmode analysis has been developed to describe the output of phase-locked injection laser arrays, showing that an array of emitters with weak coupling can only operate in a set of discrete modes determined by the number and the spacing of the emitters.
