Semiconductor Color-Tunable Broadband Light Sources And Full-Color Microdisplays

總結

Methods And Systems Are Provided That May Be Used To Utilize And Manufacture A Light Sources Apparatus. A First Light Emitting Diode Emits Light Having A First Wavelength, And A Second Light Emitting Diode For Emitting Light Having A Second Wavelength. Each Of The First And Second Light Emitting Diodes May Comprise Angled Facets To Reflect Incident Light In A Direct Toward A Top End Of The First Light Emitting Diode. The Second Light Emitting Diode Comprising Angled Facets May Reflect Incident Light In A Direction Toward A Top End Of The Second Light Emitting Diode. A First Distributed Bragg Reflector Is Disposed Between The Top End Of The First Light Emitting Diode And A Bottom End Of The Second Light Emitting Diode To Allow Light From The First Light Emitting Diode To Pass Through And To Reflect Light From The Second Light Emitting Diode.
