The bi-directional link consists of two static breadboard platforms that utilize low-SWaP, commercial off-the-shelf components. Each platform features a small form-factor pluggable optical transceiver and a programmable erbium-doped fiber amplifier on transmit. The free space link spans a 500 m line-of-sight distance between two academic buildings, namely Fitz Hall and Kettering Labs at the University of Dayton. Both platforms are indoors and transceive through existing building windows. The wavelength of operation is 1550 nm and the free space optical communication (FSOC) platforms have been previously evaluated for eye-safety. In this work, the authors demonstrate mechanical beam steering based upon de-centered lens technology, round-trip bit error rate measurements, and a free space transmission control protocol network for closed-loop operation including client-server messaging, auto-reconnects, receiver optimizations, and generalized self-healing capabilities.","PeriodicalId":19561,"journal":{"name":"Optical Engineering","volume":"143 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139647830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, assuming the collected light is focused into an optical fiber or over a sensor positioned in the focal plane, we use the ABCD ray-matrix representation to calculate the impact of atmospheric turbulence on the power in the fiber or power over the sensor. Calculation of such metrics requires the knowledge of the transmitted average power that enters the receiver aperture (power in the bucket) and the long-term beam spread in the focal plane, from which the Strehl ratio can be obtained.","PeriodicalId":19561,"journal":{"name":"Optical Engineering","volume":"1 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139414354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This makes the photon information efficiency (PIE), i.e., the number of bits that can be retrieved from a single received photon, a relevant figure of merit to characterize data rates achievable in deep-space scenarios. We review theoretical PIE limits assuming a scalable modulation format, such as pulse position modulation (PPM), combined with a photon counting direct detection receiver. For unrestricted signal bandwidth, the attainable PIE is effectively limited by the background noise acquired by the propagating optical signal. The actual PIE limit depends on the effectiveness of the noise rejection mechanism implemented at the receiver, which can be improved by the nonlinear optical technique of quantum pulse gating. Further enhancement is possible by resorting to photon number resolved detection, which improves discrimination of PPM pulses against weak background noise. The results are compared with the ultimate quantum mechanical PIE limit implied by the Gordon–Holevo capacity bound, which takes into account general modulation formats as well as any physically permitted measurement techniques.","PeriodicalId":19561,"journal":{"name":"Optical Engineering","volume":"112 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139422758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
