“…To solve the wavelength selection problem between down-and up-stream carriers and to reduce the system cost, several kinds of novel carrier-reusing schemes have been proposed recently [9]- [13]. Among these demonstrations, the most typical solution is the use of bidirectionally different modulation formats to avoid the crosstalk when injecting the data-encoded down-stream carrier into the up-stream transmitter [9]- [11]. Nevertheless, this inevitably raises the equipment cost since the typical carrier-reusing scheme requires additional modulators and receivers for transmitting two modulation formats.…”

The inherent data-erasing functionality of a 10-Gb/s colorless Fabry-Pérot laser diode (FPLD) wavelength controlled by reusing a downstream optical carrier with encoded data is explored. By operating the injection-locked colorless FPLD at high dc bias, the unique in situ data-erasing mechanism is attributed to the almost identical power-to-current slope, regardless of optical injection-locking level. When reusing the downstream carrier, the injection-locked upstream colorless FPLD can significantly suppress the extinction ratio of the residual 10-Gb/s downstream data from 7.1 to G 1 dB. This facilitates direct reuse of the downstream carrier without the need for an additional data eraser. With the data-erasing capability under 0-dBm injection, the carrier-reused upstream transmission successfully delivers on-off keying data up to 10 Gb/s with a signal-to-noise ratio of 6.2 dB and an extinction ratio of 5.4 dB. Even with a downstream injection power value of only À9 dBm, the upstream bit error rate (BER) of such a dual functional colorless FPLD biased at ! 2I th indicates a BER of G 1 Â 10 À10 . This releases the typical demand on high power budget requested for downstream data transmission and carrier reusing. The large parametric tolerances of such a data-erasable and carrierreusable colorless FPLD transmitter also facilitate its practical application in densewavelength-division multiplexed passive optical networks.
