OPTIMAL-DESIGN OF DUAL-WAVELENGTH MULTIPLE-BEAM SPLITTERS

Dual-wavelength multiple beam splitters (DWMBS's) are designed to spli t a dual-wavelength beam into two beam arrays, one for each of the two wavelengths. These two beam arrays may have either the same dimension and structure or different dimensions and structures, depending on ap plications. We present results of our computer simulations for a 1 x 5 DWMBS that exhibits one-dimensional diffraction efficiency and unifor mity of 83.8% and 98.4%, respectively, for a wavelength of 514.5 nm an d of 85.1% and 99.0%, respectively, for a wavelength of 632.8 nm.
