“…Although these ideas have attracted much attention over the years and especially the injection-or wavelengthlocking scheme has been already commercialized, further efforts have been placed to increase transmission speed per wavelength and, at the same time, to simplify the link structure by eliminating light sources such as BLS which were used in addition to the light sources used for carrying the data. As a part of the efforts, the remodulation (RM) schemes in which the downstream optical signal is reused for upstream transmission have been developed, based on the usage of an RSOA as a colorless source [9][10][11][12][13][14][15]. As shown in Fig.…”

This article presents the RSOA-based re-modulation schemes for practical application to the WDM-PON link. Emphasis is put on the three methods for reducing the residual downstream signal in the upstream transmission; the simplest one is to use the RSOA gain-saturation property, the second uses selective filtering of the adiabatic-chirped DFB-LD output spectrum, and the last uses a dynamic RSOA gain control by varying its driving current according to the incident binary signal. The reflection sensitivity in the proposed re-modulation link is also qualitatively presented in the cases of using two different types of seed light: coherent light from DFB-LD array and spectrum-sliced incoherent ASE light. We show experimental results of an error-free bidirectional gigabit transmission over 20 km at -30 dB reflection with the spectrum-sliced ASE seed light.

“…The last one could be very interesting for low-cost applications were single-port modulators that Manuscript received December 23, 1996; revised March 19, 1997 function in reflection are a good choice for fiber-to-the home (FTTH) networks. A modulation bandwidth for these systems situated between 10-50 MHz might be adequate [6]. Also, a reflective-mode spatial light modulator could be realized using this elementary device for applications like optically connected parallel machine (OCPM) fiber-to-fiber optical crossbar switches where ferroelectric liquid crystal smart pixels are usually used, with characteristic configuration times of several tenths of microseconds [7].…”

We present a new silicon-on-insulator (SOI) integrated optics structure to be used as an intensity light modulator at 1.3 m. The device consists of a waveguide Fabry-Perot interferometer. In association with a grating coupler this device could function as a spatial light modulator or a reflective-mode modulator. The Fabry-Perot reflectivity is tuned by free-carrier injection from a forward-biased lateral P + /N 0 /N + diode. Consequently, the reflected back guided-mode has an intensity that is a function of the effective index modulation in the central waveguide of the Fabry-Perot. Our numerical simulation reveals that such a structure could function for current densities not exceeding 500 A/cm 2 , with a cutoff frequency of 100 MHz. This new type of device is compatible with the mature silicon technology and could replace in applications the standard liquidcrystal spatial light modulators or for fiber-to-the-home intensity modulators.

“…The first integrated RSOA for optical communication appeared in 1996 where the device was employed for upstream signal modulation at a bit rate of 100 Mbit/s (Feuer et al, 1996). Then several experiments based on RSOAs for local access network were realized where the bit rate was increased to 155 Mbit/s (Buldawoo et al, 1997).…”
