How it works?

A small portable laser scans the object and interacts with target molecules.

After the interaction, the reflected light carries the “fingerprints” of those target molecules back into sensor-on-chip and signal analysis is carried out, where molecular information is deciphered.

Sensing is performed in a fraction of a second, which means the sensor system-on-chip offers real-time measurements.

Methods of application

In-line

BROLIS sensor may be integrated directly into industrial interface either in-line providing the fluid/substance flow-through geometry or via bypass.This configuration has the following advantages:

Real-time composition monitoring
Absolute levels + trend
Direct feedback loop for process control
Process dynamics and log option

In vitro/off-line

For handheld, home use, portable off-line applications, where the sample is measured off-line. Be it a drop of blood, saliva or industrial process product/by product. A small portion of the sample is taken from the patient or industrial process, etc., and dispensed onto BROLIS sensor for spectroscopic measurement.

Ideal for portable applications
Quick measurement for composition
Lower cost
Simple use

In vivo

Non-invasive option for remote monitoring. Most challenging from technology point of view but most rewarding from user experience:

Real-time composition monitoring
Absolute levels + trend
No invasive procedure
Wearables, hearables, etc.

Technology highlights

BROLIS’ integrated sensor is based on swept-wavelength infrared laser absorption spectroscopy. Each molecule has a unique absorption spectrum due to its various rotational-vibrational movements. This unique absorption spectrum can be used as a fingerprint for species and concentration identification.

Brolis Sensor Technology owns unique GaSb/Si fully-integrated spectrometer-on-a-chip solution in the 1800 nm – 2400 nm spectral region for a wide variety of sensing applications. Our spectrometer on chip features all-in-house technology combination of:

Extremely broadband GaSb gain-chips grown by in-house MBE
Low noise, high yield uncooled GaSb photodetectors
Custom Si photonic integrated circuit technology
In-house GaSb/Si integration technology

To tackle the sensor problem, we created a technology that did not exist before. We build everything ourselves – from exotic GaSb (Gallium Antimonide) based material synthesis, to the world’s first ultra-widely swept hybrid GaSb-Si Photonics integrated laser.
The latter allowed us to create the world’s first laser-based sensors realized in a silicon photonics chip that is smaller than 5 sq. mm. All this know-how is proprietary to BROLIS and was developed purely in-house.
