A self-mix laser unit includes: an active region having a first side and a second, opposite, side; a p-type Distributed Bragg Reflector (DBR) region, which is in direct touch with said first side of the active region; an n-type DBR region, which is in direct touch with the second side of the active region; and an n-type or p-type or other substrate. A heating unit provides modulated heating to the active region, either directly via an electrical resistor within the active region; or indirectly by passing or propagating modulated heat through one of the DBR regions or through the substrate. The modulated heating improves the laser-based self-mix signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Laser-based devices utilizing temperature modulation for improved self-mix sensing","description":"Laser-based devices utilizing temperature modulation for improved self-mix sensing.
