Symmetric Micro-optic Module

Laser-based designs have been a mainstay in optics and information transmission for decades, with a growing demand for efficient and reliable modules with minimal light beam positional drift. This demand is especially relevant as more industries explore more precise light control functions, including optical fibers and other high-tolerance applications, which will benefit from modules that maintain consistent beam focus. The challenge lies in maintaining the beam's steadiness over operational power levels, often disrupted by thermal loading imbalance. A lack of efficient heat dissipation or regulating designs can significantly affect a module's thermal loading, causing potential inconsistencies in the beam focus and eventual decline in light efficiency, which can be problematic for high-tolerance optical applications.

Technology Description

The micro-optic module features an innovative design that aligns a pair of substrates to opposing sides of a fast-axis collimating lens and a beam twister, running parallel to a neutral plane defined by the light propagation paths from an array of laser emitters. Thermal symmetry is maintained as both substrates share the same coefficient of thermal expansion and thermal conductivity. This arrangement ensures stability around the neutral plane at operational power levels. The technology differentiates itself through its compatibility with laser emitter arrays, including laser diode bars. The module’s unique thermal properties allow it to facilitate a consistently focused light beam with minimal positional drift. These features enable efficient and reliable coupling of the light beam to various high-tolerance applications, including optical fibers, marking a notable advancement in the industry.
