EOM and AOM Box

  • Idea: <fc #ff0000>PAPER FOR EOM/T CONTROL</fc>
  • <fc #ff0000>2D Skizzen rein!!!</fc>

Advantages

  1. easy to handle
  2. robust
  3. mechanics/temperature stabil
  4. active control of the temperature of the EOM

Components

Optics

  • 1x Fiber-AOM
  • 1x Fiber-EOM
  • 1x Fiber-Coupler/Splitter
  • 2-3x Fiber-rewinder (=Aufwickler)

Mechanics

  • Alu-Box (Typ: 01182810/A131)
  • Breadboard
  • Mount for AOM (Material: Alu)
  • Mount for EOM (Material: Alu, Cupper, Teflon, …)

Electronics

  • 2x SMA connectors for RF-freqeuncy
  • 1x BNC connector for out-of-loop temperature measurement
  • 1x Sub-D-9-Male connector for temperature controlling
  • 2x Peltier elements (Typ: QC-K03504T125, 189186 from Quick-Coo; Datasheet: 189186-da-01-de-peltier_element_3504.pdf)
  • 2x 10kOhm NTC (Typ: Epcos B57861S)
  • Cables for NTC´s 0.25mm^2 (max. 4A)
  • Heat-conducting paste between peltier elelements to Al-mount and peltier elements to cupper mount
  • NTC´s cables are twisted and have a shield, which is connected to earth
