Core Viewpoint - The article discusses the advancements and integration techniques in silicon photonics, emphasizing the importance of heterogeneous integration for the development of next-generation optical devices and systems [17]. Group 1: Heterogeneous Integration Techniques - Silicon itself does not emit light but is transparent at 1300nm and 1550nm, making it suitable for single-mode fiber transmission. The combination of silicon (Si) and silicon dioxide (SiO2) allows for the creation of various optical components [2]. - Grating couplers are highlighted as essential components that can rotate laser beams and couple them into silicon photonic (SiP) circuits, although they incur higher optical power loss [3]. - The addition of germanium (Ge) to silicon enables the detection of light at 1300nm and 1550nm, with SiGe technology being compatible with high-speed electronic devices [6]. - The unique properties of silicon-based modulators are crucial for the success of various SiP products, with modern CMOS technology driving this development [6]. Group 2: Integration Methods - Heterogeneous integration involves combining different material technologies into a single photonic integrated circuit (PIC), which can be achieved through processes like flip-chip bonding and micro-transfer printing [10][11]. - Flip-chip bonding requires precise alignment and can achieve high coupling efficiency, although it faces limitations in manufacturing throughput and cost reduction [11]. - Wafer bonding methods, including metal or oxide intermediate bonding and direct wafer bonding, are discussed, with direct bonding being more suitable for CMOS processes due to its lower temperature requirements [12]. Group 3: Upcoming Events and Industry Focus - TrendBank plans to host the 2025 Heterogeneous Integration Annual Conference from November 17-19, 2025, in Ningbo, focusing on advanced packaging technologies and fostering collaboration between industry and academia [17]. - The conference will cover topics such as multi-material heterogeneous integration, optoelectronic integration, and advanced packaging techniques, aiming to promote technological innovation and industry application [17].
