GaAs MSM," IEEE Photonics Technol. Lett. 15, 724 – 726 (2003)
We demonstrate 20-GHz input
bandwidth of an optoelectronic sample-and-hold circuit using optically
triggered metal-semiconductor-metal switches made of
low-temperature-grown GaAs. Linearity greater than or
equal to 4 effective-number-of-bits and an estimated 3-dB
bandwidth of up to ~63 GHz are observed for
the sample-and-hold process, making the device a potential candidate for
moderate resolution, high-speed sampling applications.
