Mid-infrared quantum cascade lasers are semiconductor injection lasers whose active core
implements a multiple-quantum-well structure. Relying on a designed staircase of …

Single-mode lasing at room temperature in quantum-cascade lasers (QCLs) with arched
cavity design has been demonstrated. The output optical power in single-mode lasing …

In this paper, we review the recent progress in broadly tunable single-mode mid-infrared
quantum cascade lasers (QCLs). With a brief introduction on various applications of broadly …

Recently, on-chip single-mode laser emissions in coupled microdisks have attracted
considerable research attention due to their wide applications. While most of single-mode …

Double-tapered laser diodes with 23rd order laterally coupled surface gratings are
fabricated at 913 nm. A narrow ridge waveguide restricts the lateral mode number, and …

We report experimental demonstration of tunable, monolithic, single-mode quantum
cascade lasers (QCLs) at∼ 10 μm with a two-section etched slot structure. A single-mode …

We employ properly designed asymmetric Mach-Zehnder interferometer structures as
effective wavelength filters and monolithically integrate them in conventional Fabry-Perot …

The peculiarities of two-state lasing in a racetrack microlaser with an InAs/GaAs quantum dot
active region are investigated by measuring the electroluminescence spectra at various …

Продемонстрирована одночастотная лазерная генерация при комнатной температуре
в квантово-каскадных лазерах с арочной геометрией резонатора. Выходная …

In this report we study the Vernier effect in coupled laser systems consisting of two cavities.
We show that depending on the nature of their coupling, not only can the “supermodes” …
