Opto-mechanical sub-systems

Sub-systems.

Pre-aligned modules that integrate TeraSpike microprobes and TeraLine on-chip devices into existing optoelectronic set-ups: probe or chip fixation, beam focusing and alignment. The new Sub-Mini series is compact; the Sub-DB series is the classic breadboard design.

Sub-Mini series

Sub-Mini-1-TR.

Functions

  • Microprobe fixation
  • Two beam paths for emitter and detector antenna, each with focusing tube and tilt mirror
  • Manual beam-to-microprobe focusing and alignment for both beams
  • Compact frame for mounting on standard optical components

Sub-Mini-1-TR is the compact module for the TeraSpike transceiver probes (TR series), which need one optical beam for the emitter and one for the detector antenna. It can also be used with detector probes.

Sub-Mini series

Sub-Mini-1-TLX.

For TeraLine TD-800 and TD-1550 on-chip devices.

Functions

  • Beam-to-sample alignment and focusing for the photoconductive switches of TeraLine chips
  • Pre-aligned on the centred sample window: only small re-adjustments needed
  • Two tilt mirrors and focus stages for both laser beams
  • Fibre couplers exchangeable for SHG-Units to run a TeraLine TD-800 with a 1560 nm laser
  • Samples mount on top; right-angled bracket for any mounting frame

Delivery

  • Sub-system Sub-Mini-1-TLX, pre-aligned
  • Right-angled mounting bracket
  • Alignment screw for the tilt mirrors
  • Optional sample spacer matching the height of a TeraLine sample

See the application notes Sub-Mini-1-TLX (PDF) and on-chip spectroscopy. A top-view alignment camera eases the alignment of the laser beams on the photoconductive switches.

Sub-DB series

Sub-DB-1.

Functions

  • Microprobe fixation
  • Manual beam-to-microprobe focusing
  • Manual beam-to-microprobe alignment
  • Manual microprobe height variation

Variant

  • Sub-DB-1-FC-AT: fibre-coupled, with mounted and aligned fibre output coupler and variable attenuator (wavelength, connector and power to specification)

The core sub-system Sub-DB-1 is a mini-board module with pre-aligned opto-mechanical components for the system integration of TeraSpike microprobes. See the application notes Sub-DB-1 (PDF).

Sub-DB series

Sub-DB-1-TR.

Functions

  • Microprobe fixation
  • Manual beam-to-microprobe focusing (for two beams)
  • Manual beam-to-microprobe alignment (for two beams)
  • Manual microprobe height variation

Sub-DB-1-TR is the classic mini-board module for the TeraSpike transceiver probes (TR series), with optics for two beams — one for the emitter and one for the detector antenna.

Sub-DB-2.

A vertical breadboard platform holding the core module Sub-DB-1 and further beam-guiding components.

Content

  • Vertical motherboard including sub-system Sub-DB-1 in customised height
  • Assembly brackets for the optical table
  • 2 alignment apertures
  • 2 pre-aligned tilt mirrors on board, one at custom height for coupling the beam in

Variants

  • Sub-DB-2-Cam: magnifying USB CCD camera for monitoring the probe-tip approach to the sample surface
  • Sub-DB-2-TR: with Sub-DB-1-TR instead of Sub-DB-1, for transceiver probes
  • Sub-DB-2-TR-Cam: both options combined

Why vertical? The vertical breadboard allows a horizontal sample, so sample placement and raster-scan stages work with gravity, not against it. See the application notes Sub-DB-2 (PDF).
