【 摘 要 】

References(7)Cited-By(1)It is noticed that drain reactance of a MESFET is significantly changed by laser irradiation, and a novel optically tunable filter is proposed. One MESFET works not only as a negative resistance, but as a tuning element. Tuning range of 104MHz is obtained in X-band by optical tuning.
