ABSTRACT: Stimulated emission of InP diodes in the 9060-9080 ; region was compared
with that of their GaAs counterparts (see Table I). InP bars were prepared by the
directed crystallization method in the form of larRe-size polycry9tals grained in the
direction of the bar axis. The bars were tellurium-doped with electron concentrations'
of 5-1017 cm-3. T'he diffusion of zinc from the gas phase into polished plates each
containing 2- 3 seeds took place at 750C over a 30-min period. The depth of the p-n
junction was 35 u. The electrical contacts were made of gold which was sputtered on
plates at 400C. The bar ends were polished and the sides were roughly worked. The
GaAs diodes were prepared in a similar manner with the following exceptions: diffusion
of zinc into GaAs lasted 4 hr at 850C under excess As pressure, and the resonator

due to a lower (than GaAs) quantum yield and to a thick active layer (8-10 V).
The differential efficiencies of the InP laaer made it possible to deliver pulsed
power of 7 watts at 75 amp at the liquid N temperature. orig. art. has: 2 tables.

ABSTRACT: Phenomenological method,; were u%ed in an experimental study of certain
properties of GaAs laser diodes (loss factor, quantum yield, differential
efficiency, gain). The specimens were prepared by the diffusion of zinc into n-type
GaAs crystals with electron concentrations of 2 x 1018 cm-3. The cavities consisted
of silver mirrors sputtered on polished crystalline surfaces pre-coated with a thin
layer of SiO, and the electrical contacts consisted of sputtered metal (Au, Ni, In,
Sn) films and fused-in electrodes. T'he measurements were carried out at 77K and the
pulsed outrut was recorded by a calibrated silicon photodiode. The lowest threshold
currents occurred in diodes which were cleaved on all four aides. A threshold current
of 25 mamp wag attained at the liquid Ile temperature and At a density of 75 amp/cm2.
C-w operation was observed from diodes with I thr ' 0.5 amp at 4.2K. The results

inilicate that the transforrmition of electr1ral powf-r Into optical power occurs with a.
yield of the order of unity and that the greatest loc;s Is due to abqnrptlon in the
megium inside the cavity. Vie loss coefficient for the better diodes was S- 10 cm-1
at 77K, a value which had been theoretically predicted elsewhere. The highest
dtfferential efficiency at 77K was 671, although it was much lower in the case of
dfodes with FabTy-Perot cavities under high threshold current densities and in four-
sided diodes with low threshold current densities. The efficiency of the p-n I Mc-
tions was 0.5-0.55 with a 25% gain, which tonk into account losses in series
resistance. Efficiencies of 602 were achieved in the case of optimal reflectivity
and cavity length. The optical gain in the subthreshold reRion was 3.10-21 cm-1.

ABSTRACT. Previous studi-s of optimal linear predistortion and
carre(tion ~Ref I to 5) have assumed fixed channel
parameters. However, in short and medium waves, long-
distance UHF scatter propagation etc, the signaIOSull fle r s
from fading. Many channels of this type may be described
as a simple single-ray channel with variable absorption.
The fading frequency is very low compared with signal
f requenc y. The random f ading process is subst itut ed by
a random quiint i t Y w I t It d t -it r ibut lon c0 Ific I d I fig w I th t lie
one-climensional disivibution of real fading, Although
this substitution ~.auses a loss of ergodicity of the
output signal, it is balanced by considering the random

Uptlmlz~ttion for minimum meari-sqAark- deviation of

termed redistort-~-r. The outplit signal is de(oded into

find the predistorter and corre~:tor which minimize the

The corrfctor parameters are varied in accordance with
data on fading obtained during the course of operation.

that this information requires a vanishingly small

with respect to maximum signal/noise ratio at the
channel output is constclered. It is shown that the only.
way that this can he a~~compllshed is by varying the
parameters of the predistorter. The fading distribution
character has no influence cn this process. At high

using the complex system with variable predistortion
and correction. Acknowledgments are made to E.L.Blobh

ABSTRACT: A procedure- -to theoretically considered for lreqiiency-band trans-
in in such a way that the mean-square deviation'of the received message from
p9s g
'that transmitted approaches a minimum which corresponds to Shannon's optimal
1conditions. The information and noise spectra are broken up into bands within
h.the 'etral densities are quasiconstant. The nurnber of bands and their
pe
widtbx are selected depending on the gen6ral conditions, required accuracy, and
Itechnical facilities. All noise bands are arranged in the order of Increasing noise

Abstract: The authors investiqnted a r,,roxip of 11 patiento with
Me c ical clinical picture of Cushing's syndrome. 2 wonen
in the group showed values of THS In the urine exce-ding I mg per
24 hours. Neither of these cases resulted from a malignant
cause. The reason for the high THS occurrence can be a chronic
case with an increased steroidogonesis, 1 Tablop 16 Western ref-
