WAVELENGTH TUNABLE OPTICAL SOURCES, FILTERS, AND DETECTORS

Configurable/re-configurable optical wavelength filter without the need for any additional optical isolator

Microelectromechanical devices for optical communications

  • Wavelength division multiplexing (WDM) technologies offer service providers not only increased transmission capacity on each fiber but also flexible and non-intrusive means to expand their networks to support evolving requirements
  • Optical systems have penetrated access networks and data centers, driving demand for improved performance, increased integration, reduced power consumption, and increased flexibility
  • Lower costs are driving the photonic component community to replace multiple discrete components and hybrid assembles with monolithically integrated circuits
  • Silicon based integrated photonics offers a platform for many optical functions through microelectromechanical systems (MEMs) and micro-opto-electro-mechanical systems (MOEMS), silicon waveguides, and integrated CMOS electronics
  • The majority of MEMs and MOEMs devices were designed for free space optical interconnections. Accordingly, it would be beneficial to provide optical component designers with MOEMs elements supporting the provisioning of tunable sources, tunable filters, tunable receivers in the planar waveguide domain without free space optics

Design of configurable/ re-configurable optical wavelength tunable components

  • The invention incorporates the design of an integrated optical device for optical micro-electro-mechanical systems-based wavelength tunable components such as sources, filters, and detectors exploiting such optical MEMs elements
  • The photonic circuit comprises a rotatable microelectromechanical systems (R-MEMs) element with a planar waveguide, diffraction grating, distributed reflector, and channel waveguide supporting propagation of optical signals
  • The new design allows making a wavelength selection, effectively reflecting a specific wavelength
  • Technology developed by Prof. Muthukumaran Packirisamy and Dr. Pierre Pottier (Mechanical and Industrial Engineering Department, Concordia University)

Competitive advantages    

  • Can be used as a wavelength filter without the need for an additional optical isolator
  • Wide tunability
  • Fast response compared to common heated mount temperature control diode laser
  • Low energy consumption and low cost
  • Small size and planar chip

Market applications

  • Telecommunications (equipment, test equipment)
  • Spectrometer
  • Optical sensing equipment (chemical, environmental and biological)
  • Product QA (Quality Assurance)

Business opportunity

  • Technology available for licensing
  • PCT/CA2016/000295
  • US patent application
