    "abstract": "We study the beaming effect of light for the case of increased-index photonic\ncrystal (PhC) waveguides, formed through the omission of low-dielectric media\nin the waveguide region. We employ the finite-difference time-domain numerical\nmethod for characterizing the beaming effect and determining the mechanisms of\nloss and the overall efficiency of the directional emission. We find that,\nwhile this type of PhC waveguides is capable of producing a highly collimated\nemission as was demonstrated experimentally, the inherent characteristics of\nthe structure result in a restrictively low efficiency in the coupling of light\ninto the collimated beam of light.",
