摘要

We describe a novel SOA-based all-optical pure-phase modulator, and show how deleterious cross-gain modulation from the SOAs can be suppressed by utilizing an integrated interferometer structure. We experimentally demonstrate the use of the optical gate as a pi/4 phase modulator producing 21.3 Gbaud 8PSK from 21.3 Gbit/s OOK and 21.3 Gbaud QPSK inputs. The modulator produces 3 dB of gain and coherent detection-based bit error rate measurements indicate a 2.4 dB excess penalty. (C) 2011 Optical Society of America

All-optical nonvolatile optical modulator for in-fiber operation

Zhihai Liu, Xiang Li, Siying Cheng, Yaru Li, Wei Jin, Yu Zhang, Yifan Qin, Yaxun Zhang, Shanshan Li, Andriy Lotnyk, Libo Yuan

Summary: The control of information is essential in the information age, and the optical modulator plays a crucial role in optical networks. All-optical modulation methods have advantages over electro-optic modulators, but require continuous power supply for processing and retaining data, resulting in increased energy consumption. We propose an integrated Ge2Sb2Te5 (GST) optical modulator for in-fiber operation, achieving modulation of output light intensity. The device demonstrates high interference intensity contrast in telecommunications bands and fast response time to pump pulses. It also operates as a scalar multiplication unit and a logic operation unit.

Transmission of 160.7-GBaud 1.64-Tbps Signal Using Phase-Interleaving Optical Modulator and Digital Spectral Weaver

Hiroshi Yamazaki, Yoshihiro Ogiso, Masanori Nakamura, Teruo Jyo, Munehiko Nagatani, Josuke Ozaki, Takayuki Kobayashi, Toshikazu Hashimoto, Yutaka Miyamoto

Summary: We demonstrate a new optical-domain bandwidth extension technology using a simple optical configuration. By using an integrated optical phase-interleaving in-phase-and-quadrature modulator (PI-IQM) with a digital spectral weaver (DSW), we can synthesize optical signals with twice the analog bandwidth of digital-to-analog converters (DACs). The PI-IQM was fabricated using an InP n-p-i-n platform and tested with driving signals generated by the DSW and DACs, achieving net data rates of 1.68 Tbps at back to back and 1.64 Tbps after 80-km transmission.

Design and analysis of all optical frequency encoded X-OR and X-NOR gate using quantum dot semiconductor optical amplifier-Mach Zehnder Interferometer

Kousik Mukherjee

Summary: In this study, all-optical frequency-encoded logic gates XOR and XNOR were designed and simulated for the first time at 1 Tb/s using quantum dot semiconductor optical amplifiers (QDSOA). The simulation included analysis of gain and phase dynamics of the QDSOA, investigation of output bit patterns using MATLAB, and calculation of key performance metrics such as Amplitude Modulation (AM) and Quality factor. The research also examined the impact of QDSOA length on quality factor and proposed modified definitions of AM and Quality Factor to apply in the context of frequency-encoded logic.

Silicon Photonic Single-Segment IQ Modulator for Net 1 Tbps/? Transmission Using All-Electronic Equalization

Essam Berikaa, Md Samiul Alam, Alireza Samani, Eslam El-Fiky, Yixiang Hu, Stephane Lessard, David V. Plant

Summary: In order to handle the increasingly large amount of data traffic, there is a continuous demand to expand the capacity of optical communication networks. Despite its limitations in electro-optic bandwidth and driving voltage requirements, silicon photonics (SiP) has significant potential as a platform for optical transceivers due to its compatibility with CMOS technology. This study presents the design and characterization of two single-segment C-band SiP in-phase quadrature modulators (IQM), and analyzes the tradeoffs in their transmission performance. The experiments demonstrate that the long IQM supports higher data transmission rates, reaching up to 413 Gbps over 80 km of standard single-mode fiber (SSMF) with all-electronic equalization and on a single polarization. By utilizing dual-polarization emulation and lookup table-based non-linear pre-distortion (NLPD), transmission rates of 827 Gbps and 800 Gbps are achieved for DP-32QAM and DP-16QAM, respectively, over 80 km of SSMF. Furthermore, a net transmission rate of 1 Tbps is achieved for DP-64QAM below the 25% overhead soft-decision (SD) FEC BER threshold of 5 x 10(-2), demonstrating the potential of SiP for next-generation 800G applications.

Qiankun Li, Xiongwei Yang, Jiali Yang

Summary: An all-optical aggregation and de-aggregation scheme is proposed for converting between one 8QAM signal and three BPSK signals using nonlinear effects in HNLF. The scheme utilizes SPM, XPM, FWM, and PA effects to decompose and recombine the signals, enabling connection between networks using different types of signals. The performance of the scheme is evaluated by calculating EVM and BER values before and after signal conversion.
