Computer design and fabrication techniques for a wideband dielectric mirror.
A computer program is used to aid in the design of a forty-seven layer wideband dielectric mirror. An integral part of the fabrication of the new design is a computerized prescription which provides a means of monitoring layer deposition. The theoretical mirror bandwidth is 6000 cm(-1) centered about 14400 cm(-1). Transmission varies between 0.6% and 2.6% with one point of 7.4% transmission at the 14400 cm(-1) center. The transmission over a wide bandwidth is obtained from the superposition and interleaving of the layers of three different wideband high reflecting mirrors. There is very good agreement between the calculated and experimental reflectance curves.
