1. A bi-directional optical communication module comprising:
a substrate;
a first band pass filter supported by the substrate;
a first optical transmitter supported by the substrate and communicably coupled with the first band pass filter, the first optical transmitter configured to generate optical signals having a first wavelength; and
a first optical receiver supported by the substrate and communicably coupled with the first band pass filter, the first optical receiver configured to receive optical signals having a second wavelength,
wherein the first band pass filter comprises a wavelength modification element configured to selectively modify a material index of the first band pass filter so as to:
pass optical signals received from the first optical transmitter having the first wavelength into an optical communication medium; and
direct optical signals received from the optical communication medium having the second wavelength into the first optical receiver.
