We put forward a scheme comprising double-stage semiconductor optical amplifiers (SOAs) for wavelength-preserving crosstalk suppression. The wavelength position of the degenerate pump in the optical phase conjugation (OPC) is optimized for signal-to-crosstalk ratio (SXR) improvement. The crosstalk suppression performance of the double-stage SOA scheme for 20 Gb\/s quadrature phase shift keying (QPSK) signals is investigated by means of simulations, including the input SXR range and the crosstalk wavelength deviation. For the case with identical-frequency crosstalk, the double-stage SOA scheme can achieve equivalent SXR improvement of 1.5 dB for an input SXR of 10 dB. Thus, the double-stage SOA scheme proposed here is more suitable for few-mode fiber systems and networks.<\/jats:p>","DOI":"10.3390\/s24196403","type":"journal-article","created":{"date-parts":[[2024,10,2]],"date-time":"2024-10-02T11:29:24Z","timestamp":1727868564000},"page":"6403","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Study of a Crosstalk Suppression Scheme Based on Double-Stage Semiconductor Optical Amplifiers"],"prefix":"10.3390","volume":"24","author":[{"given":"Xintong","family":"Lu","sequence":"first","affiliation":[{"name":"Key Laboratory of Optical Fiber Sensing and Communication Networks, Ministry of Education, School of Information and Communication Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinyu","family":"Ma","sequence":"additional","affiliation":[{"name":"Key Laboratory of Optical Fiber Sensing and Communication Networks, Ministry of Education, School of Information and Communication Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baojian","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Optical Fiber Sensing and Communication Networks, Ministry of Education, School of Information and Communication Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1186","DOI":"10.1364\/OPTICA.427631","article-title":"Space-Division Multiplexing for Optical Fiber Communications","volume":"8","author":"Puttnam","year":"2021","journal-title":"Optica"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1016\/j.yofte.2016.07.011","article-title":"Few-Mode Fiber Technology for Mode Division Multiplexing","volume":"35","author":"Mori","year":"2017","journal-title":"Opt.
