Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

With regards,

Charge of Light Transmission

Charge of Light Transmission

The modern valley of light

I’ve been thinking about Alfred, Lord Tennyson’s refrain — “Into the valley of Death / Rode the six hundred.” The poem is about courage, confusion, and a mistake that cost lives. Today the valley isn’t a stretch of Crimean mud; it’s the contested air between fibre routes, radio spectrum and sovereign infrastructure. Into that valley, a new brigade is charging — not on horseback, but on beams of infrared light.

When I first read about James Solomon (james@olee.space) and the work at olee.space, what grabbed me was the audacity: convert an idea that once belonged to laboratories — free-space optical communication (FSOC) and laser links — into field-ready systems that can carry gigabits across mountains, ships and stratospheric altitudes Source: Olee Space – Technology and reporting in the Hindustan Times.[^1]

Why this feels like a charge

  • Speed without the trench-work: Fibre is brilliant, but laying and maintaining it across mountains, seas, and contested regions is expensive and slow. Laser links promise fibre-like bandwidth with deployment measured in hours, not months.[^1]
  • Sovereignty and cost: Light doesn’t live in regulated RF bands the way radio does — that’s a freeing constraint. For countries building indigenous capabilities, that reduces dependency and licensing friction.[^1]
  • The dual edge: The same physics that lets you move terabytes also powers directed-energy systems. That’s powerful and morally complex.

My personal take — cautious optimism

I have written about light-based connectivity before: think of macro-LiFi experiments and the idea of sending data between rooftops and towers as an alternative to laying endless cable (Light at the end of the Tower?). There’s continuity here: the same impulse — use light to leap over infrastructure gaps — now runs faster and farther because photonics matured and talented teams are building robust PAT (pointing, acquisition and tracking), modulation and adaptive optics stacks.[^2]

But speed and sovereignty don’t erase responsibility. When startups pair FSOC with defence-grade use cases, we must ask: are checks and norms in place? Who governs offensive uses of directed energy? Engineering can outpace governance; that’s rarely healthy. My hope is that innovators like James Solomon (james@olee.space) and their teams prioritize transparent safety practices even as they scale.

The practical picture — what I’m watching

  • Terrestrial backbones and 5G backhaul: Buildings, towers and campuses where fibre is costly can be connected quickly using line-of-sight laser links.[^1]
  • Mobile and maritime nodes: Ships, drones and high-altitude platforms can form a mesh that extends coverage without long cable chains.[^1]
  • Quantum-resistant links and encryption at the physical layer: light can carry quantum-safe primitives — a differentiator for mission-critical comms.[^1]

A small, pragmatic wish-list for policymakers and customers

  • Faster standards alignment and testbeds so deployment isn’t caught in regulatory limbo.
  • Clear rules for defensive vs offensive directed-energy R&D, with transparency to build trust internationally.
  • Public-private test corridors — civilian, academic and defence players should stress-test links together.

Final reflection

There is a poetry to this moment: light, once a metaphor for knowledge, is now literally carrying our knowledge between peaks and ships and satellites. I admire the engineering courage at olee.space and the humility needed to build tools that can be used for both connection and conflict. When the brigade of light charges forward, I want it to be a charge of clarity — of purpose, of ethics, and of resilient infrastructure.
