A simple method was developed for the fabrication of strip waveguides in glass with losses below 1 dB/cm. A technique for the determination of the parameters of these waveguides was also developed. An integrated-optics structure was constructed from

A study was made of the efficiency of coupling of radiation from a heterostructure laser into a single-mode fiber waveguide with the aid of a hemispherical microlens formed at the entry end of the waveguide. This microlens was produced in the course

1. The proposed method of synchronizing clocks with the aid of television channels through cyclic phase changes of line pulses of the synchronization resolves ambiguities in the time count in intervals corresponding to seconds. It is not necessary to

A study was made of the degradation of injection lasers, some of which were subjected to bombardment with fast particles. It was found that the radiation defects did not accelerate the aging process during prolonged operation of the lasers. The fall

Radiation from an injection laser was modulated at frequencies up to 2 GHz by varying the pump current in a traveling-wave amplifier. A single-frequency laser with an external dispersive resonator was used as the master oscillator. The width of the o

It is shown that an effective method for selecting long-life injection lasers can be based on the initial rate of rise of the threshold current. This gives better results than the selection in accordance with the initial parameters. The aging mechani

The statistics of the failure of injection lasers was investigated experimentally in the pulsed mode at 300°K and it was compared with the Weibull distribution. A satisfactory agreement was obtained for a form parameter of 2. The influence of the re
