SUMMARY This paper reviews the operation, design, and performance of the uni-traveling-carrier-photodiode (UTC-PD). The UTC-PD is a new type of photodiode that uses only electrons as its active carriers and its prime feature is high current operation. A small signal analysis predicts that a UTC-PD can respond to an optical signal as fast as or faster than a(More)
The feeding effects of freshwater cladoceran Moina macrocopa to the larvae and juveniles of red sea bream were investigated. M. macrocopa was mass-cultured with freshwater Chlorella as feed and was enriched nutritionally with a commercial enrichment diet. Because M. macrocopa die in seawater within a few minutes, the cladocerans were frozen after(More)
