Overview
The SPL Photonics EOM-01-AA-X is a high-stability, low-voltage electro-optic phase modulator engineered for precision optical phase control in coherent laser systems and quantum optics experiments. Based on the Pockels effect in single-crystal lithium niobate (LiNbO₃), this device enables voltage-controlled, linear phase retardation of linearly polarized input light without altering beam intensity or spatial profile. Designed for integration into interferometric setups, optical frequency combs, cavity locking loops, and quantum state manipulation platforms, the EOM-01-AA-X delivers sub-wavelength phase resolution with minimal insertion loss ( 25 dB. Its compact, fiber-pigtailed architecture (FC/APC or FC/PC optional) supports direct coupling to standard single-mode fibers (SMF-28), making it compatible with Ti:sapphire, diode, and fiber lasers operating across 780–1550 nm wavelengths.
Key Features
- Electro-optic crystal: Z-cut, annealed proton-exchanged (APE) LiNbO₃ for enhanced photorefractive resistance and thermal stability
- Half-wave voltage (Vπ): Typically 4.2 V @ 1064 nm (DC–100 MHz bandwidth); scalable via external RF amplifier for higher-frequency operation up to 2 GHz
- Optical damage threshold: > 500 MW/cm² (pulsed, 10 ns, 10 Hz); > 1 W average power (CW)
- RF input: SMA female connector; 50 Ω impedance matched; integrated bias-T for DC+AC superposition
- Thermal management: Passive aluminum housing with thermal expansion coefficient matched to LiNbO₃ substrate to minimize drift
- Compliance: RoHS 2015/863/EU; CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD)
Sample Compatibility & Compliance
The EOM-01-AA-X is optimized for use with TEM₀₀ Gaussian beams from continuous-wave and mode-locked lasers. It maintains wavefront fidelity (λ/20 RMS over 1 mm clear aperture) and supports polarization-maintaining (PM) fiber inputs when paired with appropriate PM couplers. The device meets ISO 10110-7 surface quality standards (scratch-dig 10-5) and conforms to IEC 61290-1-3 for optical modulator testing methodology. For regulated environments—such as ISO/IEC 17025-accredited calibration labs or GLP-compliant photonics R&D facilities—the modulator’s traceable factory calibration report (including Vπ, insertion loss, and return loss at 1310/1550 nm) supports audit readiness. No firmware or embedded software requires FDA 21 CFR Part 11 validation, as it operates as a passive electro-optic transducer.
Software & Data Management
As a hardware-level optical component, the EOM-01-AA-X does not incorporate onboard firmware or digital interfaces. Control is implemented externally via analog voltage sources (e.g., function generators, arbitrary waveform generators, or PID controllers). LabVIEW, Python (with PyVISA), or MATLAB scripts may be used to synchronize modulation timing with data acquisition systems (e.g., oscilloscopes, lock-in amplifiers, or photon counters). All calibration datasets—including spectral response curves, phase vs. voltage linearity plots, and temperature-dependent Vπ drift profiles—are provided in CSV and HDF5 formats for integration into institutional metadata repositories or LIMS platforms.
Applications
- Laser frequency stabilization via Pound–Drever–Hall (PDH) error signal generation
- Quantum key distribution (QKD) systems requiring precise phase encoding of weak coherent pulses
- Optical coherence tomography (OCT) reference arm phase scanning
- Coherent optical communications: IQ modulation pre-compensation and carrier suppression
- Ultrafast spectroscopy: Synchronous phase shifting in pump-probe delay lines
- Atomic physics: Sideband generation for ion/atom trapping and cooling transitions
FAQ
What is the maximum optical power this modulator can handle in CW operation?
The EOM-01-AA-X is rated for up to 1 W average optical power under continuous-wave conditions, assuming proper heat sinking and collimated beam alignment within the specified 1 mm clear aperture.
Is polarization-maintaining fiber compatibility available?
Yes—custom configurations with PM fiber pigtails (PANDA or Bow-tie type) and aligned slow-axis coupling are offered upon request, with documented extinction ratio > 20 dB.
Does the device require temperature stabilization for long-term phase stability?
While the APE LiNbO₃ crystal exhibits low thermal sensitivity (dVπ/dT ≈ +0.015 %/°C), operation in environments with ±0.5 °C ambient fluctuation achieves < λ/50 phase drift over 8 hours; active TEC control is optional for sub-nanometer stability requirements.
Can this modulator be used for amplitude modulation?
No—it is a pure phase modulator. Amplitude modulation requires integration into an interferometric configuration (e.g., Mach–Zehnder or Michelson) with additional beam splitters and combiners.
