Abstract
A temperature-independent optical link for converting a received electrical signal to an analog signal. The temperature-independent optical link comprises a temperature-controlled transmitter chamber housing an ETO transmitter and a feedback-loop temperature control system. The optical link is housed in a probe head having a power supply device, and a probe tip. The temperature-independent optical link is used in a method for converting a received electrical signal to an analog signal.
Claims15
A temperature-independent optical link for converting a
- received electrical signal to an analog signal, the optical link comprising
- a temperature-controlled transmitter chamber housing an ETO transmitter, the transmitter being configured to convert an electrical signal received from an electrical input connection to an analog signal and to transmit the converted analog signal to an optical output connection,
- a feedback-loop temperature control system for controlling the transmitter chamber at a set point temperature using a temperature control device and a temperature sensor,
- wherein the transmitter chamber maintains the ETO transmitter at the set point temperature.
A method of using a temperature-independent optical link
- for converting a received electrical signal to an analog signal, the optical link comprising a temperature-controlled transmitter chamber housing an ETO transmitter, the transmitter being configured to convert an electrical signal received from an electrical input connection to an analog signal and to transmit the converted analog signal to an optical output connection and
- a feedback-loop temperature control system for controlling the transmitter chamber at a set point temperature using a temperature control device and a temperature sensor,
- wherein the transmitter chamber maintains the ETO transmitter at the set point temperature, the method steps comprising
- a. assembling the ETO transmitter and the temperature sensor in the transmitter chamber,
- b. connecting a temperature control device to the ETO transmitter and to a temperature sensor,
- c. transmitting an electrical signal to an optical input connection,
- d. converting electrical signals into optical signals,
- e. maintaining a constant temperature in the transmitter chamber, and
- f. observing a constant optical power output for a given electrical input signal.
