Abstract: A high-power electro-optic modulator (EOM) is formed to use specialized electrodes of a material selected to have a CTE that matches the CTE of the modulator's crystal. Providing CTE matching reduces the presence of stress-induced birefringence, which is known to cause unwanted modulation of the propagating optical signal. The specialized electrodes are preferably formed of a CuW metal matrix composite having a W/Cu ratio selected to create the matching CTE value. Advantageously, the CuW-based electrodes also exhibit a thermal conductivity about an order of magnitude greater than conventional electrode material (brass, Kovar) and thus provide additional thermal stability to the EOM's performance.

Abstract: A dual balance electrode trap having an outer chamber, a droplet dispenser holder removably coupled to the top surface of the outer chamber, and a rod holder having a central opening and four peripheral openings that are sized and shaped to allow four respective quadrupole metal rods to pass therethrough. The droplet dispenser holder has a top surface, a bottom surface, and a through hole that extends from the dispenser holder top surface to the droplet dispenser bottom surface. The through hole has a larger diameter portion adjacent to the top surface and a smaller diameter portion adjacent to the bottom surface, thereby preventing a droplet dispenser distal tip from extending entirely through the hole and contacting electrodes in the DBET. The rod holder is configured to be removably coupled to the quadrupole metal rods so that a location of the rod holder relative to the metal rods is adjustable.
