Is highly oriented pyrolytic graphite (HOPG) a good absorber at telecom wavelength (1550 nm)? If yes then what is the remedy for zero absorbtion?

HOPG is a good substrate for growth of h-BN. One major application of h-BN is single photon emission which can be used for telecom wavelength. Can anyone give me any insight about the absorption...
