APODIZED BROADBAND PARTIAL REFLECTORS HAVING DIFFERING OPTICAL PACKETS

摘要

A broadband partial reflector includes a first multilayer polymeric optical film having a total number of optical repeating units from a first side to a second side of the first multilayer polymeric optical film and a second multilayer polymeric optical film having a total number of optical repeating units from a first side to a second side of the second multilayer polymeric optical film and an intermediate layer on the second side of the multilayer polymeric optical film separates the first multilayer polymeric optical film from the second multilayer polymeric optical film. The first multilayer polymeric optical film has a first baseline optical repeating unit thickness profile and a first apodized optical repeating unit thickness profile monotonically deviating from the first baseline optical repeating unit thickness profile and defining the second side of the first multilayer polymeric optical film. The second multilayer polymeric optical film has a second baseline optical repeating unit thickness profile and a second apodized optical repeating unit thickness profile monotonically deviating from the second baseline optical repeating unit thickness profile and defining the first side of the second multilayer polymeric optical film.
