on chip mode Division Multiplexing switch
Optica, 2015Co-Authors: Brian Stern, Christine P. Chen, Keren Bergman, Xiaoliang Zhu, Lawrence D. Tzuang, Jaime Cardenas, Michal LipsonAbstract:Leveraging the spatial modes of multimode waveguides using mode-Division Multiplexing on an integrated photonic chip allows unprecedented scaling of bandwidth density for on-chip communication. Switching channels between waveguides is critical for future scalable optical networks, but its implementation in multimode waveguides must address how to simultaneously control modes with vastly different optical properties. Here we present a platform for switching signals between multimode waveguides based on individually processing the spatial mode channels using single-mode elements. Using this wavelength-Division Multiplexing-compatible platform, we demonstrate a 1×2 multimode switch for a silicon chip that routes four data channels with low (<−16.8 dB) crosstalk. We show bit-error rates below 10−9 and power penalties below 1.4 dB on all channels while routing 10 Gb/s data when each channel is input and routed separately. The switch exhibits an additional power penalty of less than 2.4 dB when all four channels are simultaneously routed. These results enable individual processing of multimode signals and high-bandwidth, flexible optical networks.

Poitras, Keren Bergmen, Michal LipsonAbstract:Whereas the capacity of optical-fibre networks is enhanced by schemes such as mode-Division Multiplexing, integrated photonics remains based on single-mode operation.

Simultaneous Mode and Wavelength Division Multiplexing On-Chip
arXiv: Optics, 2013Co-Authors: Lian-wee Luo, Noam Ophir, Christine P. Chen, Lucas H. Gabrielli, Carl B. Poitras, Keren Bergman, Michal LipsonAbstract:Significant effort in optical-fiber research has been put in recent years into realizing mode-Division Multiplexing (MDM) in conjunction with wavelength-Division Multiplexing (WDM) to enable further scaling of the communication bandwidth per fiber. In contrast almost all integrated photonics operate exclusively in the single-mode regime. MDM is rarely considered for integrated photonics due to the difficulty in coupling selectively to high-order modes which usually results in high inter-modal crosstalk. Here we show the first demonstration of simultaneous on-chip mode and wavelength Division Multiplexing with low modal crosstalk and loss. Our approach can potentially increase the aggregate data rate by many times for on-chip ultra-high bandwidth communications.

Performance of wavelet packet-Division Multiplexing in impulsive and Gaussian noise
IEEE Transactions on Communications, 2000Co-Authors: Kon Max Wong, Timothy N. Davidson, Qu Jin, P.-c. ChingAbstract:Wavelet packet-Division Multiplexing (WPDM) is a high-capacity, flexible, and robust multiple-signal transmission technique in which the message signals are waveform coded onto wavelet packet basis functions for transmission. We derive an expression for the probability of error for a WPDM scheme in the presence of both impulsive and Gaussian noise sources and demonstrate that WPDM can provide greater immunity to impulsive noise than both a time-Division Multiplexing scheme and an orthogonal frequency-Division Multiplexing scheme.

Time-Varying Wavelet Packet Division Multiplexing
Proceedings IWISP '96, 1996Co-Authors: Timothy N. Davidson, Kon Max WongAbstract:Publisher Summary Wavelet packet Division Multiplexing (WPDM) is an emerging Multiplexing scheme in which the properties of wavelet packet basis functions and their close relationships with perfect reconstruction filter banks are exploited to provide higher capacity, flexibility, and robustness to several adverse channel environments. In contrast to the conventional time Division Multiplexing (TDM) and frequency Division Multiplexing (FDM) schemes, the waveforms used to represent the data symbols of each user overlap in time and frequency. However, they are intrinsically orthogonal, that is, they form a wavelet packet, and therefore, the symbols can be recovered using a simple correlator receiver. The fact that the waveforms overlap in time and frequency provides an increase in capacity over TDM and FDM, and substantial robustness to adverse channel environments, while their close relationships with multi-rate filter banks provide particularly simple transmitter and receiver structures. While the wavelet packet hopping (WPH) scheme provided a general hopping framework, it required intricate implementation. This chapter shows that by giving up a little of the generality of the WPH scheme, one can avoid these technical difficulties while retaining the fundamental benefits of WPH.

on chip Multiplexing conversion between wavelength Division Multiplexing polarization Division Multiplexing and wavelength Division Multiplexing mode Division Multiplexing
Optics Letters, 2014Co-Authors: Jinghui Zou, Weili Yang, Xinliang ZhangAbstract:A compact silicon-on-insulator device used for conversions between polarization Division Multiplexing (PDM) and mode Division Multiplexing (MDM) signals is proposed and experimentally demonstrated by utilizing a structure combining the improved two-dimensional grating coupler and two-mode multiplexer. The detailed design of the proposed device is presented and the results show the extinction ratio of 16 and 20 dB for X- and Y-pol input, respectively. The processing of 40 Gb/s signal is achieved within the C-band with good performance. The proposed converter is capable of handling multiple wavelengths in wavelength Division Multiplexing (WDM) networks, enabling the conversions between WDM-PDM and WDM-MDM, which is promising to further increase the throughput at the network interface.
