Equalization of pulse timings in an excitable microlaser system with delay

Physical Review Research, 2020
An excitable semiconductor micropillar laser with delayed optical feedback is able to regenerate pulses by the excitable response of the laser. It has been shown that almost any pulse sequence can, in principle, be excited and regenerated by this system ...

Massive reduction of RyR1 in muscle spindles of mice carrying recessive Ryr1 mutations alters proprioception and causes scoliosis

The Journal of Physiology, Volume 603, Issue 22, Page 6949-6977, November 15, 2025.
Abstract figure legend Intrafusal muscles contained within muscle spindles are endowed with ryanodie receptor 1 (RyR1) calcium channels and participate in proprioceptor function. Mutations in RyR1 linked to severe RYR1‐congenital myopathies affect calcium release from both extrafusal as well as intrafusal muscles.

Full-color laser displays based on organic printed microlaser arrays

Nature Communications, 2019
In the next generation of display technology for portable devices, lasers could replace LEDs to achieve more vibrant colours. Here, Zhao et al. demonstrate a dynamic full-color display in which each pixel is made up of three printed organic microlasers ...

Enhancing thermal stability of Nd:GGG WGM microdisk lasers via silica integration

Nanophotonics
Whispering gallery mode (WGM) resonators, as an integral component of integrated photonics, have attracted considerable attention due to their high Q factor, small footprint, and small mode volume, making them widely applied as microlasers. In this work,

Selective lasing in multimode periodic and non-periodic nanopillar waveguides

, 2006
We investigate the lasing action in coupled multi-row nanopillar waveguides of periodic or fractal structure using the finite difference time domain (FDTD) method, coupled to the laser rate equations. Such devices exhibit band splitting with distinct and

Fractal modes and multi-beam generation from hybrid microlaser resonators

Nature Communications, 2018
Although fractal optical patterns have been realized previously, the direct generation of fractal modes from a laser has proven challenging. Here, Rivera et al.

Optical Phonon Lasing in Semiconductor Double Quantum Dots

, 2012
We propose optical phonon lasing for a double quantum dot (DQD) fabricated in a semiconductor substrate. We show that the DQD is weakly coupled to only two LO phonon modes that act as a natural cavity. The lasing occurs for pumping the DQD via electronic

Calibration of second-order correlation functions for non-stationary sources with a multi-start multi-stop time-to-digital converter

, 2005
A novel high-throughput second-order-correlation measurement system is developed which records and makes use of all the arrival times of photons detected at both start and stop detectors.
