  • Low-loss photonic-crystal and monolithic InP integration : Bands, bends, lasers, filters

    • Practical realizations of 2D (planar) photonics crystal (PhC) are either on a membrane or etched through a conventional heterostructure. While fascinating objects can emerge from the first approach, only the latter approach lends itself to a progressive integration of more compact PhC's towards monolithic PICs based on InP. We describe in this talk the various aspects from technology to functions and devices, as emerged from the European collaboration "PCIC". The main technology tour de force is deep-etching with aspect ratio of about 10 and vertical sidewall, achieved by three techniques (CAIBE, ICP-RIE, ECR-RIE). The basic functions explored are bends, splitters/combiners, mirrors, tapers, and the devices are filters and lasers. At the end of the talk, I will emphasize some positive aspects of "broad" multimode PhC waveguides, in view of compact add-drop filtering action, notably.

  • Modal behavior of single-line photonic crystal guiding structures on InP substrate
  • 2004
  • Ingår i: Photonics and Nanostructures - Fundamentals and Applications. - : Elsevier BV. - 1569-4410 .- 1569-4429. ; 2:1, s. 1-10
  • Tidskriftsartikel (refereegranskat)abstract
    • We have experimentally investigated the modal behaviour and the polarization dependence of the transmission through single-missing-row photonic crystal (PC) straight guides, bends and combiners, fabricated on InP substrate. A photonic crystal-based taper has been included to funnel light in these strongly confined structures. Two-dimensional finite-difference time-domain simulations have been performed and favorably compared with the measurements. It is found that the scattering process occurring at a bend/combiner transition plays a key role on the overall transmission.

  • High-bandwidth transmission of an efficient photonic-crystal mode converter
  • 2004
  • Ingår i: Optics Letters. - 0146-9592 .- 1539-4794. ; 29:15, s. 1745-1747
  • Tidskriftsartikel (refereegranskat)abstract
    • We have investigated both theoretically and experimentally the spectral behavior and the transmission and reflection performance of a photonic-crystal (PhC) mode converter upon an InP substrate. This taper exhibits 70% transmission efficiency on an 80-nm bandwidth when it couples a ridge access guide to a strongly confined single-missing-row PhC guide. Such a taper design included in a PhC bend contributes a large benefit to the overall transmission budget of the PhC-based link.
