Abstract
There has been much interest in the modification of spontaneous emission in artificial photonic structures, including photonic band-gap structures, microcavities, and low-dimensioned photonic structures. Recently, low-dimensioned photonic structures, such as microdisks1 and photonic wires,2 have been used to realize novel lasers with dimensions and characteristics much different from lasers with conventional structures. Photonic- wire structures are strongly guided onedimensional waveguides with tightly-confined mode area. It was shown that in a strongly guided waveguide, the photonic density of states can be modified, leading to a significant modification of spontaneous emission in the waveguide.3
