Gain-switched lasers are in demand numerous quantum applications, particularly, systems of key distribution and various optical random number generators. The reason for this popularity is natural phase randomization between gain-switched laser pulses. idea such has become so familiar that most authors use it without regard to the features operation mode they use. However, at high repetition rates pulses or when generated a bias current close threshold, condition may be violated. This paper...
The dependence of the semiconductor laser wavelength on pump current is a well-known phenomenon, which generally attributed to change in refractive index active layer due carrier injection. This effect usually considered be drawback as it causes frequency chirping pulses produced via direct modulation. Here, we show that at high values thermal resistance diode, lasing red-shifted caused by and this shift may significantly exceed (in absolute value) blue related induced We propose benefit...
Abstract To achieve high characteristics of single-photon detectors based on WSi thin films it is necessary to provide film thickness uniformity more than 95%. This paper presents a mathematical modeling the an ultra-thin formed by magnetron sputtering from two sources, experimentally determined mass flow single magnetron, depending location magnetrons relative substrate holder. According results non-uniformity modeling, requirements for design and unit in chamber were made, which ensured...
Superconducting single-photon detectors (SNSPD) are receivers in optical systems for space communications and exhibit high quantum efficiency count rate. The receiver the system of atmospheric communication should provide highly efficient detection radiation with a wavelength 1.55 µm. cut-off SNSPD is maximum at which maintained depends on geometrical parameters sensitive element detector thickness structure thin film superconducting material parameters. In this work, we simulate depending...
