AGC's Micro Lens Array (MLA) is a high-precision optical component designed for demanding Co-Packaged Optics (CPO) applications. Built on AGC's advanced glass platform, it delivers the accuracy, thermal stability, and scalability required for next-generation optical interconnects.
Micro Lens Array - Precision Glass Optics
Micro Lens Array Shapes Light with Precision and Flexibility
AGC's MLA is an optical component that integrates multiple micro-scale lenses with high precision, enabling functions such as collimation, coupling to optical fibers or waveguides, and light diffusion. It contributes to higher performance and greater integration of optical systems.
With submicron-level lens shape accuracy, flexible array pitch design, and support for both single-sided and double-sided arrays, AGC also offers surface coatings, such as anti-reflection (AR) films. Fine-pitch lens arrays with lens pitches down to several tens of micrometers can be fabricated, making MLA suitable for a wide range of applications.
Technical Features
Submicron-Level Lens Shape Accuracy
AGC's MLA is a high-precision optical component designed for demanding CPO applications.
High-Precision Pitch Control
Lens-to-lens pitch tolerance of ±0.3 µm or better ensures accurate alignment with Fiber Array Unit fiber arrays and silicon photonics PIC Input/Output ports. Tight pitch control eliminates cumulative alignment errors in high-channel-count configurations.
Single-Sided and Double-Sided Array Structures
Supports both single-sided and double-sided lens structures, enabling greater design flexibility. Double-sided arrays allow integrated beam conditioning without additional optical components.
Surface Coating Capability
AR coatings minimize surface reflections and maximize optical throughput. Coating specifications can be customized based on operating wavelength (e.g., 850 nm, 1310 nm, 1550 nm).
Fine-Pitch Micro Lens Arrays With Lens Pitches Down to Several Tens of Micrometers
Supports the fabrication of highly dense micro lens arrays, contributing to miniaturization and high integration of optical systems.
Custom Design Capabilities
Square Lens Design
Supports non-circular lens geometries such as square lenses, allowing more efficient area usage and compatibility with specific optical system layouts.
Multi-Row Array Configuration
Supports multi-row lens arrangements (e.g., 40ch × 2-row, 42ch × 2-row) for high-bandwidth CPO links. Multi-row designs enable higher channel density while maintaining pitch accuracy across all rows.
Prism-Integrated Micro Lens Array
Prism structures integrate with the lens array, enabling angled beam delivery to PIC-side Si lenses. This eliminates the need for separate prism components and simplifies the optical assembly in edge-coupler and vertical-coupler configurations.
Aspherical Lens Profiles
Aspherical lens designs with customizable conic constants allow optimized beam shaping within the constrained form factor of CPO connector assemblies. This provides additional freedom for coupling optimization that spherical lenses cannot achieve.
Applications
Co-Packaged Optics
Enhances optical coupling efficiency and enables precise beam shaping in highly integrated optical modules, supporting next-generation high-speed data transmission.
Optical Communication Devices (switches, transceivers, etc.)
Improves coupling accuracy between optical components such as fibers and waveguides, contributing to higher performance and reduced optical loss in communication systems.
Others (High-brightness LEDs, OLEDs, and micro-LEDs)
Enables efficient light extraction, uniform illumination, and beam shaping, supporting advanced display and lighting applications.
