| Popis: | A new optical wavelet division multiplexing (WDM)-transceiver module has been designed and fabricated for optical access networks. Conventional 1.3/1.55-/spl mu/m WDM-coupler and Y-branch were replaced by a new wavelength-selective coupler in order to reduce module size. A new WDM-photodiode (PD), which was photosensitive to 1.3 /spl mu/m light and transparent to 1.55 /spl mu/m light, and a 1.55-/spl mu/m PD were arranged in series along the optical axis. An MQW-FP-LD was used as a 1.3-/spl mu/m transmitter. Fundamental characteristics were measured and discussed. Evaluation results, P/sub out/ of 0 dBm, responsivity of 0.36 A/W at 1.31 /spl mu/m and 0.74 A/W at 1.55 /spl mu/m, and IMD2 of -76.2 dBc, imply that this WDM-transceiver module design is promising to application for optical access networks. |
