“…SV-DD receiver is polarization independent. Although several prior DD schemes have demonstrated dual-polarization modulation and reception [11], [12], the transmitter complexity approaches that of the POL-MUX coherent systems. Several IM-DD based 100G schemes [15], [16] provide the options for the short reach application with transmission distance below 20-km, while SV-DD provides a scheme with much wider application field.…”

Data center interconnect has stimulated the research on the short-reach communications with data rate beyond 100G per wavelength and transmission distance of hundreds of kilometers. Aiming at the high-speed short-reach communications, we recently proposed the Stokes vector direct detection (SV-DD) that realizes a linear complex optical channel similar to the coherent detection. In SV-DD, the transmitter places the signal and the carrier onto the orthogonal polarizations, while the receiver achieves the polarization insensitive 3-D detection in the Stokes space with the digital signal processing enabled polarization acquisition. SV-DD achieves 100% spectral efficiency with reference to the single-polarization coherent detection, and simultaneously attains the receiver phase diversity and the cancellation of photo-detection nonlinearity. We experimentally demonstrate the SV-DD signal transmission over 160-km standard single-mode fiber at data rates of both 80 and 160-Gb/s. SV-DD significantly decreases both the system hardware and DSP complexity compared with the polarization multiplexed coherent detection, while increases the system spectrum efficiency compared with the conventional intensity modulation direct detection. Therefore, SV-DD offers a cost-effective solution for the 100G per wavelength and beyond metropolitan area network (MAN). It also owns the potentials to be deployed in the future high-speed passive optical network (PON).

“…So short-reach networks within distance of hundreds of kilometers, need to increase their capacity per wavelength beyond 40 or even 100 Gb/s [1][2][3][4][5] to meet the everincreasing traffic demand. Different from long-haul communications, these short-reach networks require massive number of transceivers across diverse geographic zones.…”

“…Therefore, lowering the system cost becomes a priority for short-reach networks. Direct detection (DD), especially a host of self-coherent (SCOH) systems [3][4][5][6][7] is suitable for short-reach applications since they can significantly lower the expense compared with coherent counterpart while achieving both high data rate and moderate reach. However, to remove SSBN, early SCOH systems leave frequency gaps at spectrum to separate signal and the signal-to-signal beat noise (SSBN) [6].…”

“…Recently, blockwisephase switching (BPS) [4] and signalcarrier interleaved (SCI) [5] DD schemes are proposed to make full use of the frequency band. Some schemes have demonstrated dual-polarization modulation and reception [3,8], but with the transmitter complexity approaching POL-MUX coherent systems. Moreover, none of the above-mentioned DD methods achieves 100% SE, except the approach employing a sophisticated narrow optical filter for optical carrier extraction [9], which can be potentially expensive and difficult to operate.…”

Abstract-We propose a scheme to implement the Stokes vector single-ended direct detection (SV-DD) using a 3×3 coupler hybrid. A 112-Gb/s single-polarization modulated 16-QAM signal is successfully received after 240-km SSMF transmission. SV-DD using 3x3 couplers may provide a more cost-effective and more power-efficient solution to achieve 100G short-reach transmission with high spectral efficiency and low system complexity.

“…Furthermore, no local oscillator (LO) is required at the receiver. Several concepts of SCO-OFDM have been proposed [6][7][8]. Similar to the RF-pilot-tone phase noise compensation concept for CCO-OFDM [3,5], SCO-OFDM is realized by sending an optical carrier (or pilot-tone) along with the OFDM signal.…”
