In this letter, we experimentally demonstrate a novel receiver-side perturbation approach to cancel the self-phase modulation and cross-phase modulation for superchannel systems using three independent receivers. With the inverse perturbation theory, we develop a nonlinear compensation model that does not require knowing the transmitted symbols and therefore avoids the penalty from the estimation error. We implement the PB-NLC in a \u0000<inline-formula> <tex-math>$3times 24.5$ </tex-math></inline-formula>\u0000 GBaud 64-QAM comb-based superchannel system spaced at 25 GHz.

In particular, common-mode noise (CMN) suppression is critical to improving the system’s ability to detect weak signals. In this letter, an innovative method for reducing noise in white-light-driven sensors is proposed. This structure fully utilizes the broad spectrum of white light and the wavelength selectivity of fiber gratings. The proposed CMN suppression method is capable of suppressing the phase noise of the light source, as well as the noise due to environmental disturbances. The experiments demonstrate that the noise floor of this vibration sensor is about -88 dB/Hz above 30Hz with 10km disturbed transmission fiber. The max 1/f noise reduction can reach approximately 60 dB near 5 Hz, while the max transmission path noise suppression exceeds 103 dB at hundreds of Hz. The proposed structure has the potential to achieve higher resolution in wavelength division multiplexing (WDM) sensor arrays without excessive cost.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142450893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to pixel array detectors, the centroid detection of this sensor is accomplished by a single point detector, which has higher sampling speed. We developed a mathematical model of optical mask-based centroid detection and verified its validity through simulation. Then, we built an experimental platform and realized high-accurate centroid detection.

Specifically, deterministic algorithms struggle to achieve sufficient accuracy, while iterative algorithms consume excessive time, thereby limiting their practical application. To address this issue, we propose a deterministic-iterative integrated phase retrieval algorithm, that is, an approximate phase, which could be quickly obtained by the deterministic algorithm, is imported as an initial value into the iterative algorithm to retrieve more accurate result efficiently. To demonstrate the effectiveness of this algorithm, we simulate its performance under various iterations and diffraction distances. Additionally, experiments are conducted using a pure-phase USAF1951 target and fixed mouse fibroblasts to verify its feasibility, high accuracy, and rapid iterative convergence speed. Integrating the deterministic and iterative algorithms, this method offers a novel approach for enhancing phase retrieval.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An additional feedback loop with almost the same time delay as the primary loop produces a low-frequency microwave signal, which is coupled into the primary loop to lock the OEO’s mode. The experimental results show that the mode-locked fundamental and the 5th-order harmonic OEO with both repetition rates of 930 kHz are realized. Under the fundamental and 5th-order harmonic mode-locking states, the single-sideband (SSB) phase noise at 10 kHz frequency offset is measured to be −92.16 dBc/Hz and −102.22 dBc/Hz, respectively. Compared to the previously reported actively mode-locked OEO with an external injection signal, our scheme does not require external signal injection and the MFCs can be stably locked when the fiber (200m) in the loop is heated from 35°C-65°C, which can overcome the problems of modulated signals and mode spacing detuning in long-term operation with more flexible and universal characteristics.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
