Numerical simulation and experimental studies of longitudinally excited miniature solid-state lasers
Publikováno v:
Applied optics. 27(5)
We present a numerical model for the transient response of a longitudinally pumped miniature solid-state laser. The model is suitable for both regenerative amplifiers and oscillators, provided the latter run in a single mode. The results of our calcu

A new boundary condition is presented for use in beam propagation calculations that passes outgoing radiation freely with minimum reflection coefficient (as low as 3*10/sup -8/). In conjunction with a standard Crank-Nicholson finite difference scheme

A new beam-propagation method is presented whereby the Pade approximant wide-angle propagation operator is factored into a series of simpler Pade (1, 1) operators, thus leading naturally to a multistep method whose component steps are each solvable b

A simple formalism is reported for studying the modes of an infinite two-dimensional (2-D) phase-locked array of vertical-cavity surface-emitting diode lasers. In this approach, the Helmholtz equation is approximately separated into products of solut

Numerical modeling of two-photon-resonant sum-frequency mixing in mercury vapor predicts efficiencies >10% for generation of 130.2-nm oxygen resonance light. The modeling indicates that power broadening of the two-photon resonance due to amplified sp

Presents on the fabrication of a ten-element antiguided (leaky-mode) diode laser array that operates in an in-phase mode with a diffraction-limited far-field pattern at drive currents up to 8.7 times the threshold current (pulsed) and an output power

The large refractive index difference between silicon nitride and silicon dioxide allows silicon nitride/dioxide waveguides to have a small mode size and low radiation bending loss. Low radiation bending loss enables high quality (Q) factor microring

Resonant subwavelength gratings (RSGs) offer narrowband high reflectivity with low-reflectivity sidebands. Analysis with the commonly used rigorous coupled-wave analysis assumes an RSG with infinite lateral extent and illumination by plane waves. Thi

Photonic crystals offer considerable promise as means of achieving ultra-compact photonic circuitry. It can be shown that most of the devices common in ordinary planar waveguide circuitry, such as splitters, MMIs and couplers, can be reproduced using

A systematic method for the design of arrayed resonant subwavelength gratings is described. Design goals are peak reflectance of unity, narrow spectral bandwidth, and low sideband reflectivity for use in an arrayed grating structure.
