Advantages

Usability

• Small and light
• No external optics needed - simple optical integration
• Direct spectrum readout
• Broadband operation
• Range and resolution can be adjusted (Operation at 10.6um, and resolution down to 2nm have been demonstrated)

Manufacturability

• Non-imaging design scales down to single chip
• Planar structures fabricated via optical lithography and dry etch (no curved surfaces, ruling, or imprint)
• Fused silica substrate compatible with Si production lines
• Folded optical path allows for integration of additional optical elements to expand capabilities

Roadmap

Our current products are the first demonstration of our technology. Our roadmap covers a number of initiatives to further reduce size and expand capabilities including the move to surface mount chip packaging and extension further into the NIR.
