The reflection spectrum of the multimodal interference is strongly integrated with the surrounding ambient humidity. An enhanced humidity sensitivity of -0.639 dB/%RH over the humidity range of 25-76 %RH is achieved. The sensor is experimentally investigated for two applications: human breathing and soil moisture. The response/recovery time for human breathing is 0.82 s/0.86 s. And a high sensitivity of −0.439 dB/%RH is obtained in the soil moisture range of 36-74.9 %RH.

However, its realizations are traditionally sophisticated with locking circuits required, limiting its wide applications. In this letter, we break this limit by devising the first optical locking MOPA laser, with seed source of a MOPA fiber laser self-injection locking to a high-quality (Q) nonlinear fiber resonator (NFR). The self-injection locking MOPA laser reaches a spectral linewidth of 3.9kHz at its maximum output power of 4.78W, which is \u0000<inline-formula> <tex-math>$sim 5.5times 10 ^{mathbf {2}}$ </tex-math></inline-formula>\u0000 linewidth reduced from the free running state. An up to 50-nm bandwidth of four wave mixing (FWM) spectrum is generated from the NFR, at 4.78-W output power of the self-injection locking MOPA laser. Such locking regime is environmentally stable, owing to the frequency pulling effect of the locked seed source to the NFR. This work paves an all optical locking scheme for high power external cavity enhancing optical systems, which will benefits nonlinear spectrum generations in a more simple, high efficiency and high linewidth performance way.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142260125","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}

Arm locking is a technique, with which the laser frequency can be stabilized to the intersatellite arm length, to further reduce the risk of time delay interferometry (TDI). Clock noise is one of the main sources limiting the ultimate performance of arm locking. In this work, we experimentally demonstrate arm locking with a transfer oscillator, by using an electrical delay unit. We develop a low-noise transfer oscillator based on the laser frequency comb, which can coherently generate a clock signal traceable to the stabilized laser. The transfer noise can achieve \u0000<inline-formula> <tex-math>$4.2times 10~^{{-8}}$ </tex-math></inline-formula>\u0000 Hz/Hz\u0000<inline-formula> <tex-math>$^{{1/2}}$ </tex-math></inline-formula>\u0000 at 0.7 mHz, and \u0000<inline-formula> <tex-math>$2.7times 10~^{ {-7}}$ </tex-math></inline-formula>\u0000 Hz/Hz\u0000<inline-formula> <tex-math>$^{ {1/2}}$ </tex-math></inline-formula>\u0000 at 0.1 Hz. We examine the performances of single-arm locking and modification of dual-arm locking. The experimental results show that, with the help of the transfer oscillator, the noise performance of arm locking can be improved, since the clock noise has been removed. Moreover, we carry out TDI after the implementation of arm locking, and the noise performance can well meet the requirement of GW detection. Our work could provide a valuable method for the frequency-comb based arm locking and TDI in the future space-borne GW detections.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200576","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}

The theoretical derivation shows that the timing error and phase noise can be independently compensated. In this Letter, we propose a timing recovery (TR) algorithm based on an absolute timing error detector (Abs TED) and a pilot-based carrier phase recovery (CPR) to eliminate the timing error and phase noise separately. An experiment for 25G NOMA-PON is set up to verify the feasibility of the proposed algorithms. The weak ONU can achieve the 20% soft-decision forward error correction limit after compensating for timing error and phase noise.
