Parameter

Distinct Features  of SLS Technology

 

Band Alignment

n      Type 11 Band Alignment

 

 

Dark Current

n      Very low dark current due to: reduced Auger recombination

 

 

Performance

n      Higher Performance (D*λ) due to:  reduced dark current

 

 

Operating Temperature

n      Higher Operating Temperatures due to: reduced dark current

-         Uncooled (300K), T.E. Cooled (160K, 200K, 250K) &  Cryo-Cooled (77K)

 

Minority Carrier Lifetime

n      Longer lifetime  due to:  reduced Auger recombination

 

 

Array Speed

n      Very High Speed (100ns)

 

 

Spectral Range

n      Wide Spectral Range (1-22 μm)

- Single Band (SWIR:1-3 µm, MWIR:3-5 µm, LWIR: 8-12 µm, VLWIR1:10—16 µm, VLWIR2:16-22 µm)

- Co-Located Dual Band  and  Co-Located Triple Band Layouts

 

Array Uniformity

n      Higher array uniformity due to: GaSb-based process steps and SLS material growth

 

 

Cost

n      Lower Cost due to:

 - higher array uniformity and array yield

- elimination of cryo-cooler for SWIR, MWIR & LWIR arrays

- elimination of three-stage cryo-cooler for VLWIR arrays

 

Weight, Size & Power

n      Light weight compact system with low power  consumption
