“…The VIPA in that experiment was tunable from −1100 to −1500 ps/nm, and had a 100-GHz FSR. In 2002, H. Ooi et al from Fujitsu [138] used VIPA compensators to provide optimized post-compensation for each channel in the transmission of 88 channels at 43 Gbps over 600 km of NZDSF using the C and L-bands. The broadband tunability feature of the VIPA is quite appealing both for laboratory and field use.…”

Chromatic dispersion compensation is an integral part of WDM transmission system design. Compensator properties such as insertion loss, dispersion slope and effective mode area have a large impact on WDM system performance due to nonlinear optical propagation effects. Dispersion compensator imperfections, such as multi-path interference, group delay ripple, insertion loss ripple and limited per-channel compensation bandwidth, place additional limitations on the achievable transmission distance and capacity. In this paper, a survey of key WDM transmission system experiments is undertaken to 1) review the development of chromatic dispersion compensation technologies, 2) discuss the device characteristics that most impact system design for each technology, and 3) hopefully enable the reader to better evaluate compensator technologies for specific applications.

“…[13,14] When the VIPA is used in combination with a grating, this 2D disperser can generate an angular dispersion 10-20 times larger than that of solely grating, and spatially disperse the overlapping free-spectral-range (FSR) orders along the y-axis. This approach has been successfully applied in various contexts, such as wavelength (de)multiplexers, [15][16][17][18] dispersion compensators, [19][20][21][22] wavelength-parallel polarimeters, [23] high-resolution spectrometers, [24] single-pixel imaging, [25] programmable amplitude and phase shaping, [26,27] mechanicalscanning-free spectrally encoded 2D imaging, [14,28] and solidstate frequency-modulated continuous-wave LiDAR with 2D spectral scanning. [13,29] However, these 2D-dispersive systems lack WSS functions, because they cannot direct the returning beam into an output port with an adjustable offset to the input port at the same end of the light path.…”

“…[13,29] However, these 2D-dispersive systems lack WSS functions, because they cannot direct the returning beam into an output port with an adjustable offset to the input port at the same end of the light path. As a result, these systems either require a circulator to allow the light signal to exit directly after the port where it entered, [21,26,27] or have an output port located at another end of the system from the input port. [15,16,18] On the other hand, a VIPA-based WSS [3] without a grating has demonstrated to achieve a spectral resolution of 3 GHz and a spectral coverage of only 1.5 THz, which is insufficient to cover the basic C-band of 4 THz.…”

Ultrabroadband 2D‐Dispersive Wavelength Selective Switch with 1.57 GHz Hyperfine Spectral Resolution and >1600 Channels

Wavelength selective switches (WSSs) are key components in commercial reconfigurable optical add/drop multiplexer systems that are essential for future wavelength‐division multiplexing (WDM) networks. With rapidly increasing data transmission, there is a demand for high‐capacity WSSs. However, in a WSS, the number of channels, which is related to the ratio of its band coverage relative to spectral resolution, is limited within a certain range, since the 1D dispersion of the grating fails to utilize the 2D selectivity of the liquid crystal on silicon (LCoS) pixel array in the “disperse and select” architecture.. To surpass this limitation, here a virtually imaged phased array (VIPA) is employed into the WSS system to expand 1D‐dispersion into 2D space in order to fully utilize the 2D selectivity of LCoS. According to the experimental results, this VIPA‐grating‐based 2D WSS approach enables a spectral resolution that can be narrowed to 1.57 GHz (18 times improvement from 1D WSS, and massive (>1600) WDM channels can be predicted) and ultrabroadband spectral coverage across the S‐, C‐, and L‐bands of 20 THz. The data communication performance of the 2D WSS is also tested.
