The OCTLIGHT VCSEL Swept Source is unique in using monolithic MEMS-VCSELs similar to 9xx nm datacom VCSELs and a single material MEMS system similar to proven MEMS timing solutions. The Caliper VCSEL Swept Source is a complete subsystem which includes efficient optical coupling and amplification of the VCSEL together with wavelength sweeping of the MEMS using low voltages.
For applications where a flexible scan rates is desired, such as to switch between several scan modes, we offer the Swept Source Caliper-FLEX.
For applications where a fixed scan rate is needed, we offer the Swept Source Caliper-HERO. The patented Highly Efficient Resonant Oscillator (HERO™) technology achieves fast scan rates into the MHz range by operating the MEMS in vacuum with a simple and low-voltage drive signal. This provides several benefits including:
- High phase stability
- Long-term stable wavelength sweep
- Symmetric bi-directional sweep
- High reliability due to the absence of MEMS catastrophic failure
The long-term stability makes efficient high throughput data acquisition possible using a single-channel DAQ with pre-calibrated FFT linearization.
