This study introduces a micro gradient-index conical lens with a significantly larger acceptance angle than traditional microlenses. Simulations and experiments confirm its enhanced optical performance, offering a fourfold improvement in acceptance angle.

Area of Science:

  • Optics and Photonics
  • Micro-optics

Background:

  • Conventional microlenses have limitations in acceptance angle, restricting their use in certain optical systems.
  • Gradient-index (GRIN) optics offer potential for improved lens performance.

Purpose of the Study:

  • To present a novel micro gradient-index conical lens design.
  • To simulate and compare the performance of different index profiles and cone shapes.
  • To experimentally validate the simulated performance of fabricated lenses.

Main Methods:

  • Simulation of micro gradient-index conical lenses using commercial optical design software (CodeV).
  • Comparison of lens performance based on varying refractive index profiles (e.g., Gaussian) and cone shapes.
  • Fabrication and experimental testing of conical lenses to measure acceptance angle.

Main Results:

  • Micro gradient-index conical lenses demonstrate a four times larger acceptance angle compared to conventional microlenses.
  • Conical lenses with a Gaussian-index profile exhibit superior acceptance angles over those with a solid refractive index.
  • Fabricated lenses achieved an acceptance angle exceeding 27 degrees at a 50% detection threshold, aligning with simulation predictions.

Conclusions:

  • Micro gradient-index conical lenses offer a significant advancement in acceptance angle for micro-optical applications.
  • The Gaussian-index profile is advantageous for maximizing acceptance angles in conical lens designs.
  • The study validates the effectiveness of simulation tools for designing and predicting the performance of advanced micro-optical components.
