This study introduces a novel photodetector featuring a multilayer structure comprising a subwavelength grating, a Ge absorption layer, and a SiO2/Si multilayer. By utilizing the phase-matching coupling of SiO2/Si-confined modes, the devices with the gratings demonstrate a high absorbance peak of ∼97% with an ultra-narrow linewidth of ∼1 nm at 1550 nm. It is 10 times narrower than those of previous works of photodetectors integrated with phase-matching gratings. By utilizing the two-dimensional grating, the device performs polarization independently. Additionally, the inclusion of a Si spacer layer enhances design flexibility while maintaining performance. With a demonstrated bandwidth of approximately 58 GHz, the proposed photodetector is well-suited for high-speed optical communication applications. This work provides a pathway to overcoming current limitations in photodetector efficiency and spectral control, paving the way for future innovations in photonic devices.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-10"},"PeriodicalIF":2.1,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10946127","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The single-tone signal utilizes a phase-shift method for high-precision ranging, while the pseudo-random code is employed to solve the distance ambiguity problem in the phase-shift method. The merging of the pseudo-random code with the single-tone signal in the digital domain and the data processing in the digital domain achieve simultaneous modulation and simultaneous ranging, which ensures the complete synchronization of the two signals during both transmission and processing. Furthermore, the pseudo-random code is band-limited, which ensures that the pseudo-random code signal and the single-tone signal do not overlap spectrally, thus preventing interference between them. The experimental results indicate that the ranging accuracy is 59.84 <inline-formula><tex-math>${bf mu m}$</tex-math></inline-formula> and the ranging precision is 14.72 <inline-formula><tex-math>${bf mu m}$</tex-math></inline-formula>.

This paper reviews a breakthrough of a long-distance hollow core fiber (HCF) fronthaul (up to 11.1 km) able to meet the requirements of B5G optical mobile networks, where the transmission medium is common to both 5G NR and PoF signals. This work is placed in context and compared with results provided by other authors, showing the relevance of the outcomes and subsequent future possibilities. It also creates a discussion in which the performance of other fiber technologies may be compared, as new B5G fronthauls with special attention paid to transmission in a single fiber, avoiding noise transfer between high power laser PoF source and 5G-NR data that affects the signal quality. PoF energy delivery efficiencies are also analyzed, achieving up to 9.9 % efficiency (from launched optical power to electrical power on the load) for a 3.1 km HCF and 0.9 % for a 11.1 km HCF. The PoF signal is used to supply a Bluetooth Low-Energy load.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-10"},"PeriodicalIF":2.1,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11016695","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144243847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these systems face challenges related to high cost and complexity, especially in short-reach coherent optical communication systems. To address these issues, we present a low-resolution coherent optical communication system with low-complexity adaptive equalizer. The system's performance is evaluated in a 5 km 28 GBaud 16 QAM transmission scenario. The simulation results indicate that error-feedback noise shaping (EFNS) is highly effective in suppressing digital-to-analog converter (DAC) quantization noise, thereby reducing resolution demands on the DAC. Furthermore, the adaptive equalizer, based on a Stokes-domain depolarization scheme (SS-AEQ), achieves a 45% reduction in the complexity of the equalization algorithm. Compared with the 8-bit resolution DAC and the traditional 2 × 2 MIMO AEQ scheme, the system, employing 4-bit DAC for low-resolution transmission, achieves low-complexity equalization while maintaining comparable transmission performance.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 2","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10944222","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a solution for EDFA, cladding pump has gained attention due to its low cost and high gain. This paper presents a cladding pump coupler (CP) based on double cladding passive optical fiber (DCF), fabricated using the fused taper technique, which supports the transmission of four modes: LP01, LP11, LP21, and LP02. The optical loss of this device is less than 0.3 dB, and it does not introduce new crosstalk in the transmission line, ensuring excellent mode beam quality. The fabricated device is fusion-spliced with a four-mode erbium-doped fiber (EDF), achieving very low splice loss. The EDFA based on this device exhibits outstanding performance. In the C-band, it can achieve an average gain greater than 21.56 dB, with an average differential mode gain (DMG) of 1.42 dB. When amplifying four modes simultaneously, the gain exceeds 19.21 dB, the DMG is less than 2.51 dB, and the noise figure (NF) is less than 7.348 dB. This is of great significance for enabling long-distance signal transmission in mode-division multiplexing systems.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"17 3","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10938589","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
