Non-volatile trimming of photonic micro-rings using integrated and electrically programmable phase-change elements [Invited]

Xingyu Zhang, Nathan Rooney, Sadra Rahimi Kari, Nicholas A. Nobile et autres

Photonic integrated circuits (PICs) are constantly finding new applications, yet their performance is frequently compromised by unavoidable fabrication errors. Conventional post-fabrication correction methods are often irreversible or power-intensive, limiting the scalability of photonic systems. In this work, we introduce a non-volatile and …

Incorporating Si into Sb2Se3: Tailoring Optical Phase Change Materials via Nanocomposites

Chih‐Yu Lee, Yi‐Siou Huang, Felix F. Adams, Chuanyu Lian et autres

Chalcogenide-based optical phase change materials (OPCMs) exhibit a large contrast in refractive index when reversibly switched between their stable amorphous and crystalline states. OPCMs have rapidly gained attention due to their versatility as nonvolatile amplitude or phase modulators in various photonic devices. …

GSID: Generative Semantic Indexing for E-Commerce Product Understanding

Haiyang Yang, Qinghe Zhang, Liyu Chen, Chuanyu Lian et autres

Structured representation of product information is a major bottleneck for the efficiency of e-commerce platforms, especially in second-hand ecommerce platforms. Currently, most product information are organized based on manually curated product categories and attributes, which often fail to adequately cover long-tail products …

Multi-Value-Product Retrieval-Augmented Generation for Industrial Product Attribute Value Identification

Haiyang Yang, Yun Yan Su, Liyu Chen, Chuanyu Lian et autres

Identifying attribute values from product profiles is a key task for improving product search, recommendation, and business analytics on e-commerce platforms, which we called Product Attribute Value Identification (PAVI) . However, existing PAVI methods face critical challenges, such as cascading errors, inability …

Microheater hotspot engineering for spatially resolved and repeatable multi-level switching in foundry-processed phase change silicon photonics

Hongyi Sun, Chuanyu Lian, Francis Vásquez, Sadra Rahimi Kari et autres

Nonvolatile photonic integrated circuits employing phase change materials have relied either on optical switching with precise multi-level control but poor scalability or electrical switching with seamless integration and scalability but mostly limited to a binary response. The main limitation of the latter …

Integrated PN Microheaters for Fast and Efficient Control of Phase-Change Photonic Memory

Sadra Rahimi Kari, Marcus Tamura, Zhimu Guo, Yi‐Siou Huang et autres

We present a multifunctional photonic memory cell integrating PN junctions with phase change materials. This enables nonvolatile coarse tuning and high-speed volatile fine tuning for faster modulation and higher efficiency than prior thermal or carrier-based approaches.

High-speed multifunctional photonic memory on a foundry-processed photonic platform

Sadra Rahimi Kari, Marcus Tamura, Zhimu Guo, Yi‐Siou Huang et autres

The integration of computing with memory is essential for distributed, massively parallel, and adaptive architectures such as neural networks in artificial intelligence (AI). Accelerating AI can be achieved through photonic computing, but it requires nonvolatile photonic memory capable of rapid updates during …

IPL: Leveraging Multimodal Large Language Models for Intelligent Product Listing

Kang Chen, Qinghe Zhang, Chuanyu Lian, Yixin Ji et autres

Unlike professional Business-to-Consumer (B2C) e-commerce platforms (e.g., Amazon), Consumer-to-Consumer (C2C) platforms (e.g., Facebook marketplace) are mainly targeting individual sellers who usually lack sufficient experience in e-commerce. Individual sellers often struggle to compose proper descriptions for selling products. With the recent advancement of …
