NetTest TUNICS series tunable external cavity laser

Detailed explanation of TUNICS series products

1. TUNICS Plus: Flagship High Performance Tunable Laser

TUNICS Plus is the culmination of years of technical accumulation by NetTest, with the following core functions:

Active mode free control: ensuring continuous scanning across the entire frequency band;

High output power: up to+10 dBm;

Wide tuning range: with a maximum width of over 150 nm and a resolution of 1 pm;

Multiple modulation methods: supports amplitude modulation and mode locking operations;

Wavelength monitoring and external calibration: It can be linked with the wavelength meter through GPIB or RS-232 interface to achieve closed-loop wavelength control;

Sub MHz frequency fine-tuning: supports linewidth broadening (coherent control) function.

TUNICS Plus offers multiple wavelength range options, such as Sxx (short band), SC (S+C), CL (C+L), etc., to meet the testing needs of different bands.

2. TUNICS Purity: ASE noise free pure light source

TUNICS Purity has further improved the spectral purity based on TUNICS Plus:

ASE noise free output: patented intracavity filtering design;

Wavelength accuracy: ± 50 pm (internal reference);

Output power: up to+3 dBm;

Application scenario: Testing of high dynamic range devices, such as filters, AWGs, etc.

The purity of its output spectrum allows users to obtain high-precision test results without the need for additional configuration of tracking filters or spectral analyzers.

3. TUNIS-BT: Economical high-performance desktop laser

TUNICS BT offers the core features of the TUNICS series at a more compact size and more economical price:

Tuning range: 80 nm (optional 1440-1520, 1480-1560, 1520-1600, 1560-1640 nm);

Resolution: 1 pm;

Output power: Standard 0 dBm, optional+6 dBm or+10 dBm;

Applicable scenarios: General optical experimental platform, teaching and basic research and development.

4. TUNIS-OM: Modular manual tuning light source

TUNIS-OM is designed specifically for multi wavelength testing systems, supporting up to 8 modules integrated into a 19 inch chassis:

Tuning range: 70 nm (1500-1570 nm or 1530-1600 nm);

Resolution: better than 10 pm;

Modulation capability: 10 kHz to 1 GHz;

Power options: Standard>0 dBm, optional+6 dBm or+10 dBm.

Its multi turn knob design makes wavelength adjustment extremely intuitive, suitable for laboratory environments that require frequent manual wavelength adjustment.

OSICS Platform: Modular and Scalable Testing System

OSICS is a new generation modular optical testing platform launched by NetTest. Its core module, OSICS-ECL, is based on TUNICS technology and provides high-precision tunable external cavity laser output

Control mode: front panel control or IEEE-488/RS-232 remote control;

Resolution: Standard 10 pm, optional 1 pm;

Wavelength range: Same as TUNIS-BT;

Power options: 0 dBm standard, optional+6 dBm or+10 dBm;

Module mixing and matching: It can be mixed with DFB, ASE, EDFA, LD and other modules to build a multi wavelength and multi-functional testing system.

The OSICS platform is particularly suitable for automated testing systems that require multi-channel and high flexibility, such as optical transceiver module production line testing, optical amplifier performance evaluation, etc.

Application scenarios and technological value

1. DWDM system testing

The high wavelength accuracy, no mode hopping scanning, and wide tuning range of TUNICS series lasers make them an ideal choice for DWDM system testing. Whether it is channel spacing testing, filter response measurement, or gain spectrum scanning of optical amplifiers, TUNICS can provide stable and reproducible excitation light sources.

2. Analysis of Optical Device Characteristics

For devices such as optical filters, multiplexers, and demulsifiers, TUNICS Purity's pure spectrum can achieve high-precision measurements of insertion loss, isolation, polarization related loss, and other parameters without the need for additional filtering equipment.

3. Integration of automated testing systems

The TUNICS series supports GPIB and RS-232 interfaces across the entire range, and provides LabVIEW drivers for easy integration into automated testing environments. The OSICS platform further supports the mixing and matching of multiple modules to meet the construction requirements of complex testing systems.

4. Research and Teaching

TUNIS-BT has become an ideal choice for university laboratories and research institutions due to its economy and high performance. Its intuitive operating interface and stable output are suitable for teaching demonstrations in courses such as laser principles and fiber optic communication.
