U of Arizon, U of Rochest, U of central florida. They offer programs in Optics. For other schools, Optics is one branch research field in either physics department or EE department. Maybe Olkloha state U also offer the optics program. Qq.$!$
Applying for EE departments is very very hard. I suggest that you should apply for either optics or physics program. ds+K7B$
Good luck.
