OPTIMAS Project: Multi-Domain Laser Communications Network

1. Global Objective

The primary mission of OPTIMAS is to define and develop a secure, high-speed, multi-domain laser communications network. This infrastructure is based on the implementation of high-capacity (Gbps) bidirectional optical systems, featuring:

  • QKD Integration: Advanced study of Quantum Key Distribution capabilities for enhanced security.
  • Satellite Interoperability: Utilization of LEO, MEO, and GEO constellations.
  • Multi-Domain Connectivity: Ensuring seamless, secure links across Space, Air, Naval, and Land domains, including shore-based C5ISR centers.

OPTIMAS will provide critical communications support for ISTAR (Intelligence, Surveillance, Target Acquisition, and Reconnaissance) missions, enabling both manned and unmanned aircraft to collect and relay high volumes of sensitive data in complex operational scenarios.

2. Specific Objective: The ALCoS Prototype

A core focus of this project is the design of a prototype for an Airborne Laser Communication System (ALCoS).

Key Features & Integration:

  • Platform Versatility: Designed for integration into various aircraft; specifically envisioned for the future EuroMALE RPAS currently under development.
  • Bidirectional Links: The prototype will focus on demonstrating robust Air-to-Space optical link capabilities.
  • Environmental Optimization: The design phase includes dedicated activities to assess and mitigate atmospheric and environmental impacts on laser performance.

3. Testing and Scalability

To validate the system’s effectiveness, a Live Test Campaign will be conducted to evaluate Air-to-Ground and Space-to-Ground optical links.

  • Strategic Architecture: The OPTIMAS prototype is built on modular and scalable principles, ensuring it can be easily adapted to naval and land domains or upgraded with emerging technologies in the future.

Underwater Laser Communication System

This section outlines the primary tasks for the development and testing of the underwater optical communication infrastructure.

1. Point-to-Point Optical Communication

The objective is to establish a direct line-of-sight (LOS) link using high-precision optical components. Key activities include:

  • Hardware Assembly: Integration of transmitter and receiver units using state-of-the-art Commercial Off-The-Shelf (COTS) components.
  • Optical Design: Design and assembly of specialized optical systems, including beam expanders, to optimize signal propagation.
  • Test Environment Setup: Configuration of the water tank facilities to replicate underwater operational environments.
  • Channel Characterization: Analysis of attenuation and scattering parameters to simulate various maritime conditions (e.g., turbidity, salinity).
  • Protocol Testing: Execution of communication trials across different modes:
    • Simplex (One-way)
    • Half-Duplex (Time-slot based)
    • Full-Duplex (Simultaneous bidirectional)

2. Diffuse Optical Communication

This phase focuses on non-line-of-sight (NLOS) or wide-angle connectivity to increase link robustness.

  • Lens System Adaptation: Modification of the optical assembly to support diffuse light emission and reception.
  • Comparative Testing: Execution of the same validation battery used in the point-to-point phase to benchmark performance and reliability under diffuse conditions.

3. The PULSE Hackathon is a 48 hour competition for students co-organized by monodon and uVigo’s QoPHI LAB.

In this challenge, students from all over europe are invited to work together and solve a problem around Underwater Optical Communication. The ultimate goal is to create innovative solutions at the time that we provide an opportunity for students to take contact with real world / industry problems and learn more of this field of study.

PULSE HACKATHON 2026

  • From 8 to 10th of july
  • Vigo, Spain (Campus de Vigo, As Lagoas, Edificio Miralles)
  • Open to 40 students that will work in teams of 5 to 6 persons.
