摘要： A VCSEL can include: one or more quantum wells having (Al)InGaAs; two or more quantum well barriers having Al(In)GaAs bounding the one or more quantum well layers; and one or more transitional monolayers deposited between each quantum well layer and quantum well barrier, wherein the quantum wells, barriers and transitional monolayers are substantially devoid of traps. The one or more transitional monolayers include GaP, GaAs, and/or GaAsP. Alternatively, the VCSEL can include two or more transitional monolayers of AlInGaAs with a barrier-side monolayer having lower In and higher Al compared to a quantum well side monolayer that has higher In and lower Al.

摘要： A method of detecting the properties of a printing target in a printing apparatus capable of performing a recording process on the printing target. The method uses a vertical cavity surface emitting laser disposed in the printing apparatus and comprises transporting the printing target through the printing apparatus, emitting a wavelength modulated optical signal toward the printing target using the vertical cavity surface emitting laser, receiving a reflection of the wavelength modulated optical signal, and analyzing the reflected optical signal to identify a property of the printing target.
摘要翻译：一种在能够对打印目标进行记录处理的打印设备中检测打印目标的属性的方法。该方法使用设置在打印设备中的垂直腔表面发射激光器，并且包括通过打印设备传送打印目标，使用垂直腔表面发射激光器向打印目标发射波长调制的光信号，接收波长调制的反射光信号，并分析反射的光信号以识别打印目标的属性。
