We demonstrate the effects of varying the injection barrier thickness and injector doping level on current transport and gain bandwidth in a lambda ~ 8.2 mum quantum cascade laser.
The effect of current fluctuations on the linewidth of semiconductor lasers is analyzed using the single-mode rate equations.
Films of (Y(3-x-y)Bi(x)Pb(y))(Fe(5-z)Ga(z))O12 (z = 0 to 1. 1) and (Y(3-x-y) Bi(x)Pb(y))(Fe(5-w)In(w))O12 (w = 0 to 0.6) garnets were prepared by liquid phase epitaxy.
Among the optical sources presently available for optical communication applications, AlGaAs light-emitting diodes1,2 and injection lasers3,4 are probably the most compatible with low-loss optical
We examine the effect of Landau level mixing on the braiding statistics of quasiparticles of abelian and nonabelian quantum Hall states.
The authors report the growth of 6-, 9-, and 12-layer InAs/InP quantum-dash-in-a-well (DWELL) laser structures using gas source molecular beam epitaxy.
A formula for computing the output spectrum of a system with a bounded transfer function, when the input consists of the sum of a few (practically, up to 3) pure sinewaves and, possibly a "noise" t
Acoustic crosstalk cancellation is a signal processing technique whereby two (or possibly more) loudspeakers are used to deliver desired signals exactly at the listener's ears.
Using direct measurement the effect of macro-bending on the dispersion in dispersion compensating fibres was investigated.
Wireless service providers striving to improve the coverage of their systems or enlarge the cells' size can choose either one or a combination of two different diversity techniques, namely, microdi
