Optical Limiters and Sensors

Directed energy weapons are an emerging capability that may cause a paradigm shift in battlefield engagement. Protection from these weapons is a key facet to maintaining the United States’ operational capabilities and military superiority. HAMR has addressed the problem by developing a patent pending optical limiting technology currently in its second Phase II STTR. As we further develop this technology, we seek partners in the aerospace and defense industries who may benefit.

Capabilities and concepts include:

  • Application specific coating design

  • Broadband protection

  • Tailorable pass-through transmission

  • Laser Testing

HAMR has developed a patent pending optical limiting technology for protection of sensitive components.


 

PCSEL arrays can provide several hundred kilowatts of power over a full wafer.

High Energy, Low SWaP Semiconductor Lasers

High energy lasers are utilized in applications ranging from industrial cutting and welding, to military defensive capabilities, to potentially unlocking fusion power. The highest power lasers are typical chemical/gas or solid state fiber, and tend to suffer from low efficiency and large, cumbersome systems. Semiconducting lasers offer high efficiencies with compact form factors that can leverage the production scaling of todays fab network. HAMR is developing a photonic crystal surface emitting laser technology which aims to provide extremely high beam quality and brightness while producing powers comparable to solid state and chemical/gas lasers.

Capabilities and concepts include:

  • Laser testing

  • Photonic crystal and array design

  • Thermal evaluation


EM Modeling

Prediction of electromagnetic behavior is a critical step in the development of electrical and electro-optic devices. At HAMR, EM modeling is routinely employed to evaluate new device, component, and coating designs . This enables a rapid iteration cycle and reduction in costly experimentation, allowing us to develop and efficiently produce novel technologies such as radomes, antennas, windows, and optical coatings.

Capabilities and concepts include:

  • Optical limiters

  • HEL sensors

  • Non-linear material simulations

  • Radome design

  • Metasurfaces, frequency selective surfaces, and photonic crystals

 

In-house EM modeling capabilities are leveraged to develop new electronic and elecro-optic technologies through tools such as Ansys, COMSOL, and custom MATLAB code.
