Optical receiver with optical feedback
Electronics Letters, 1987 A new optical receiver with optical feedback is described. The optical feedback is implemented by feeding back a fraction of the light from an optical source which is connected to the output of the receiver, to an extra photodiode. The proposed theoretical model was found to be in good agreement with measurement results on a 5 MHz optical receiver.

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Regulating the Single-Mode Lasing Intensity of Semiconductor Lasers Without Wavelength Shift
IEEE Photonics Journal, 2020 A simple method to regulate the single-mode lasing intensity of semiconductor lasers without wavelength shift is demonstrated in this paper. The basic component is a digital micro-mirror device (DMD), which can be taken as an adjustable two-dimensional ...

A Stable Optical Trap from a Single Optical Field Utilizing Birefringence [PDF]
, 2016 We report a stable double optical spring effect in an optical cavity pumped with a single optical field that arises as a result of birefringence.

Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Breakthroughs in Photonics 2013: Passive Mode-Locking of Quantum-Dot Lasers
IEEE Photonics Journal, 2014 Most recent achievements in passive mode-locking of quantum-dot lasers, with the main focus on jitter reduction and frequency tuning, are described. Different techniques, leading to record values for integrated jitter of 121 fs and a locking range of 342

Dissipative solitons in pattern-forming nonlinear optical systems : cavity solitons and feedback solitons [PDF]
, 2005 Many dissipative optical systems support patterns. Dissipative solitons are generally found where a pattern coexists with a stable unpatterned state. We consider such phenomena in driven optical cavities containing a nonlinear medium (cavity solitons ...

Laser optical feedback imaging controlled by an electronic feedback loop [PDF]
Journal of the Optical Society of America A, 2013 In autodyne interferometry, the beating between the reference beam and the signal beam takes place inside the laser cavity and therefore the laser fulfills simultaneously the roles of emitter and detector of photons. In these conditions, the laser relaxation oscillations play a leading role, both in the laser quantum noise, which determines the signal ...
