Methods in molecular biology (Clifton, N.J.)·2025

We developed custom optical filters using CMOS technology. This method allows for multiple, specific filter responses on a single chip for advanced optical applications.

Area of Science:

  • Photonics
  • Integrated Optics
  • Materials Science

Background:

  • Monolithic integration of optical filters is crucial for advanced photonic systems.
  • Existing methods may lack flexibility in tailoring filter responses.
  • Complementary metal-oxide-semiconductor (CMOS) platforms offer a scalable solution for integrated photonics.

Purpose of the Study:

  • To present a novel method for fabricating monolithically integrated CMOS optical filters.
  • To demonstrate the capability of producing filters with diverse and customer-specific spectral responses.
  • To enable multichanneling capabilities on a single chip.

Main Methods:

  • Utilized a Fabry-Perot resonator design with Bragg mirrors and a patterned cavity.
  • Tuned filter responses by altering geometric parameters of the cavity patterning.
