To overcome this, we propose a hardware‐algorithm isomorphic photonic neural cryptosystem tailored for exact data delivery. This architecture intrinsically utilizes physical optical scattering as the random projection of an Extreme Learning Machine (ELM). By synergizing the ELM's rapid closed‐form analytical inference with the deterministic error tolerance of structured data encoding, we successfully bridge the gap between statistical neural network inference and cryptographic correctness, achieving a 100% Decryption Success Rate (DSR). Furthermore, multi‐synaptic connections are repurposed as an additional physical key dimension, enlarging the key space without incurring digital computational overhead. Generating high‐entropy ciphertexts (>7 bits) and massive‐length unclonable physical keys (>96.9 megabits), the hardware‐rooted Physical Unclonable Function (PUF) coupled with a digital probabilistic encoding (salting) strategy neutralizes advanced cryptanalysis, including chosen‐plaintext attacks (CPA), known‐plaintext attacks (KPA), and machine‐learning model‐extraction attempts. Requiring only ∼0.76 M parameters and 0.67 ms inference latency, this lightweight framework natively supports high‐frequency dynamic key updates and poses a substantial computational barrier (digital keys >6 megabits) to brute‐force attacks, offering a scalable and highly efficient solution for secure communications in edge computing and IoT.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"27 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149130531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report a field‐aligned p‐SnSe/n‐ZnO/p‐Si heterojunction that converts the conventional competition between PV and PTE effects into constructive coupling. Comparative p‐SnSe/n‐Si, p‐SnSe/n‐ZnO/n‐Si, and p‐SnSe/n‐ZnO/p‐Si devices were fabricated to clarify the roles of the ZnO interlayer and the Si conductivity type. Experiments and finite‐element simulations indicate that ZnO improves carrier extraction and interfacial charge transport, whereas p‐type Si reconfigures the dominant internal electric field and suppresses polarity reversal. The optimized p‐SnSe/n‐ZnO/p‐Si device therefore delivers stable unipolar photovoltage generation over 330‐1550 nm under zero bias.
