Loss-compensated optical Y-branch switch in InGaAsP-InP

Loss-compensated optical Y-branch switch in InGaAsP-InP

An InGaAsP-InP loss-compensated Y-branch switch is demonstrated. Integrated amplifying sections compensate for internal losses. The operating wavelength is 1.3 mu m, and the gating dynamic range is 35 dB. A study of similar devices indicates that a gain of more than 10 dB and a gating dynamic range...

Zusammenfassung:An InGaAsP-InP loss-compensated Y-branch switch is demonstrated. Integrated amplifying sections compensate for internal losses. The operating wavelength is 1.3 mu m, and the gating dynamic range is 35 dB. A study of similar devices indicates that a gain of more than 10 dB and a gating dynamic range in excess of 45 dB are feasible.< >
