Implication

Experimental characterization demonstrates high acousto-optic efficiency in crystalline germanium, highlighting its potential as an infrared modulation standard.

Key Points

To measure the acousto-optic properties of crystalline germanium and perform a complete characterization of its photoelastic tensor for infrared device applications.
Measured acousto-optic interactions across crystalline germanium specimens.
Characterized the full photoelastic tensor components and calculated the acousto-optic figure of merit.
Germanium demonstrated a substantially larger acousto-optic figure of merit than other infrared materials, with the single exception of crystalline tellurium.
Superior mechanical integrity and optical properties make germanium preferable to tellurium for infrared beam deflection and modulation.
Germanium was established as a proposed reference standard for infrared acousto-optic material studies, analogous to fused silica in visible spectrum applications.
