Abstract

We employ a spatial-light-modulator-based colorless photonic spectral processor with a spectral addressability of 100 MHz along 100 GHz bandwidth, for multichannel, high-resolution reshaping of Gaussian channel response to square-like shape, compatible with Nyquist WDM requirements.

Experimental layout making use of the PSP for shaping to a rectangular spectrum with the liquid crystal on silicon (LCoS) spatial light modulator (SLM). The SLM applies linear phase tilts to each spectral component for encoding coupling losses to the desired spectral shape.

Fig. 2.
Fig. 2.

Proposed method for generating a Nyquist-WDM superchannel: odd square channels (marked in blue) are generated using an on-grid PSP filtering the output of a 100 GHz ITU grid demultiplexer, while even square channels (marked in red) are generated using an off-grid PSP filtering the output of a 100 GHz shifted ITU grid demultiplexer.

Fig. 3.
Fig. 3.

Experimental results of PSP filter width change, one column at a time. For each position, 10 dB attenuation is reached at less than 5 GHz bandwidth. Although the system has 100 MHz addressability, the filter edge position is shifted here in 400 MHz increments for clarity only.

Fig. 4.
Fig. 4.

Experimental results of rectangular spectral filter response, compensating a commercial multiplexing filter (marked with dashed-black line) for three selected bandwidths: 30, 40, and 50 GHz. (a) Cascaded flattened spectrum for three bandwidths. As the bandwidth becomes larger, overall filter attenuation must be increased in order to achieve equalization. (b) Encoded PSP response without the multiplexer [different colors match those of (a)]. The dashed-purple line denotes the PSP response without any spectral shaping, showing a flat response along the entire usable bandwidth.

Fig. 5.

Time-domain measurements of (a) 30 GHz, (b) 40 GHz, and (c) 50 GHz carved spectra, resulting in 33, 25, and 20 ps width sinc2 shaped pulse intensities, respectively, measured with a high-speed sampling scope. The measured temporal results are plotted as solid color lines, matching the bandwidth filters of Fig. 4. Expected sinc2 functions with the desired widths are plotted as dashed black lines, showing an excellent match to the measured results.

Experimental demonstration of optical N-WDM filtering. (a) SLM pattern for on-grid channel filtering with varying phase tilts along the central 50 GHz and large constant phase tilt outside, and (b) SLM pattern for the off-grid channel filtering with varying phase tilts along the outer 50 GHz and large constant phase tilt along the center. Resulting (c) on-grid and (d) off-grid PSP spectral response. (e) On-grid and (f) off-grid Gaussian response of multiplexer, simulated with Finisar WaveShaper. Cascaded spectral filtering response for (g) on-grid and (h) off-grid, yielding interlaced rectangular shaped channels with 50% duty cycle. (i) Passively combined on-grid and off-grid components of each branch, resulting in full spectral coverage with <1dB ripple.
