Unlike traditional LSCs, HLSCs focus on converting energy from one part of the solar spectrum (typically green) to a specific range (usually red) and aim for the converted photons to exit the device from the bottom surface rather than the edge surfaces. Thus, beyond spectral conversion, HLSCs are especially notable for their light extraction capabilities. Efficient spectral conversion and outcoupling efficiency are achieved by optimizing luminescent materials and introducing light extraction techniques. In this study, we start by examining the specific requirements of horticulture to clarify the motivation for using HLSCs. We re-evaluate and propose new optical metrics tailored to HLSCs. Additionally, we analyse potential loss channels for direct red emission and converted red emission. Utilizing Monte Carlo ray tracing method and experimental data, we further explore the factors influencing these loss channels. The key evaluation metrics for HLSC and LSC are compared to highlight the distinctions between the two, emphasizing the innovative features of the HLSC device. Our work provides a fundamental discussion on HLSCs and offers design guidelines for future HLSC research.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 6: Photon. for Climate Chng.

Associated with this is a need to scale capacities of short-reach optical transceivers towards multiplex Terabit/s, while maintaining integration density (frontpanel or beachfront density) and energy efficiency (pJ/bit). One option to scale transceiver capacity is to increase the bandwidth per lane from today's 200 G to 400 G or even higher: coherent transceiver technology is then expected to play an ever more important role. Photonics and electronics with higher bandwidths beyond 100 GHz will play a crucial role. Integration of thin-film LiNbO3 modulator onto a Silicon Photonics platform is shown to be a viable option to meet the needs for new generations of optical transceivers. Front-end electronics such as linear modulator drivers and transimpedance amplifiers can rely on traveling-wave design approaches to allow continued bandwidth scaling despite (relative) slowing transistor speeds. Novel wireline data converter architectures can be used to overcome limitations of existing implementations. Maintaining signal integrity from photonics and electronics can be facilitated using both 2.5D and 3D integration approaches. While the introduction of novel materials and architectures will require time to further mature, optical transceivers operating at baudrates up to and beyond 200 Gbaud are now just beyond the horizon.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 3: AI/ML Integrated Opto-electronics","pages":"1-16"},"PeriodicalIF":4.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143521527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantum communication protocols based on entanglement offer an inherent quantum based randomness for key generation and provide in general higher security compared to prepare and measure implementations. Moreover, the future quantum internet will also be based on the distribution of entanglement for securely connecting quantum computers in a network. In this work we show the feasibility of using sequential time-bin entangled states for quantum key distribution in metropolitan networks using off-the-shelf components. The time-bin encoding ensures high fidelity distribution robust against random polarisation fluctuations occuring in optical fibers. Modulated laser pulses in the GHz frequency range are used to generate time-bin entangled photon pairs. The entangled photons are then sent over an about 30 km long (9.5 dB loss) fiber link within the Vienna fiber network, showing high degree of distributed entanglement with a measured 93% quantum visibility.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 5: Quantum Materials and Quantum Devices","pages":"1-8"},"PeriodicalIF":4.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their reliable output power is often limited by catastrophic optical mirror damage (COMD), primarily caused by self-heating and elevated facet temperatures. Despite advancements in material growth, facet passivation, epitaxial design, and packaging, reliability remains a significant issue. This study introduces two innovative waveguide designs to mitigate self-heating and enhance reliable output power: a 2-section waveguide and a distributed waveguide (DWG). Both designs separate the heat-generating lasing region from the output facet by incorporating a passive section that is electrically isolated but optically connected to the laser section. The 2-section design places a long passive section near the facet, significantly reducing its temperature, while the DWG design employs periodic lasing and passive sections to enhance heat dissipation along an extended cavity length. Experimental results show that both designs effectively lower facet temperatures below the laser body temperature, enabling higher power operation. The 2-section lasers achieve COMD-free operation under high power, thereby improving reliability. These results demonstrate that advanced waveguide structures can significantly enhance the reliability of the laser output facet and pave the way for semiconductor lasers with significantly increased lifetime.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 2: Pwr. and Effic.

This study reinterprets the linewidth narrowing mechanism in external-cavity diode lasers (ECDLs) from a perspective that the noise-induced frequency fluctuations are suppressed by the rapidly varying phase in frequency domain introduced by the external cavity. We highlight the importance of the localized high slope in the rising edge of the feedback spectrum in forming stable narrow linewidth laser modes. Based upon this understanding, we introduce an alternative to traditional Lorentzian optical feedback. We demonstrated that asymmetric lineshapes, such as Fano, can serve as the optical feedback of ECDLs with enhanced performance. Theoretical analysis and numerical simulations reveal that Fano-based external cavity lasers, benefiting from a feedback spectrum with a steeper local slope than Lorentz-based cavities, can achieve superior linewidth narrowing under the same fabrication conditions. This study offers a novel approach for the design and application of narrow linewidth laser diodes.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 5: Quantum Materials and Quantum Devices","pages":"1-7"},"PeriodicalIF":4.3,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
