Factors contributing to the photogenerator's effectiveness were the large number of diode elements, N=30, a high short-circuit responsivity, r=0.025 A/W, and a low saturation current, I/sub s/=3.95 nA. As a demonstration, the photogenerator was connected to a MEMS optical shutter to build a novel self-powered optical power limiter that might be used to implement autonomous signal power control in optical communication networks. It is expected that the high voltage generated by this device can facilitate the design of a large variety of useful optically powered long-wavelength lightwave circuits.","PeriodicalId":213868,"journal":{"name":"Conference Proceedings.

A specific contact resistance of 4 10/sup -5/ 1/2 cm/sup 2/ has been measured between buried contacts and the n-type InP.

This structure takes advantage simultaneously of both the high electron mobility at low field in the InGaAs channel and the low impact ionization coefficient in the InP channel. The transistor actually shows good dynamic performances and high breakdown voltage: for a 0.8 /spl mu/m gate length we obtained: gm=240 mS/mm, Idss=225 mA/mm, Vbrd=6.5 V, f/sub t/=35 GHz, f/sub max/>90 GHz. A specific feature of this HEMT structure is its low output conductance (gm/gd=40 at both low and high frequency) attributed in particular to the fact that the barrier layer is undoped, with the /spl delta/-doping sitting in the middle of the channel. For the 0.8 /spl mu/m gate length devices investigated, the output conductance is much lower than for single or dual channel HEMTs fabricated with similar geometry. This feature is maintained for shorter gate length (at Lg=0.2 /spl mu/m). In this paper an analysis of this output conductance is presented, illustrating the importance of impact ionization and residual traps.","PeriodicalId":213868,"journal":{"name":"Conference Proceedings.
