Abstract
A cavity-resonator-integrated guided-mode resonance mirror (CRIGM) shows a narrowband reflection-phase variation. Laser oscillation of a vertical-external-short-cavity laser consisting of a CRIGM and a gain mirror was demonstrated for the first time, to the best of our knowledge. The oscillation wavelength stayed at around 1045 nm even when an air-gap length between the GRIGM and the gain mirror was varied by 0.35 μm. The dependence of an oscillation wavelength on the air-gap length was reduced by one order of magnitude in comparison to a case using a multilayer mirror instead of the CRIGM. This wavelength insensitivity expands positioning tolerance in fabrication and in operation to be suitable for surface-mounting a vertical-cavity laser on a photonic integrated circuit.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
