Abstract: Acoustical ringing which results from piezoelectric effects in an electro-optical modulator is suppressed by mounting the modulator crystal between massive, acoustically absorbent, support members which also provide an electric circuit interface for applying electric signals to the modulator. Solder provides such an absorbent mounting for a lithium tantalate electrooptical modulator crystal. Both solder support members are applied during the same heating interval and permitted to cool simultaneously. In one embodiment the solder application is accomplished in a first step wherein mounds of solder are applied adjacent to the crystal at a first temperature and in a second step wherein additional solder is applied at a lower temperature between the crystal and the solder mounds.
