Abstract
This invention discloses a waveguide filter device including a necked waveguide having a relatively broad input end which receives light and allows propagation of multi-mode light waves therethrough, a narrowed neck portion at which higher modes radiate outside the waveguide and only the modes which can propagate therethrough pass therethrough and a relatively broad output end.
