Abstract
A transistor for emitting laser with a fixed frequency includes a first region, a second region, at least one quantum well, and a third region. The at least one quantum well is installed in the second region, and the second region is coupled between the first region and the third region. When one of the first region, the second region, and the third region receives two signals, or two of the first region, the second region, and the third region receive the two signals respectively, the at least one quantum well emits the laser with the fixed frequency.
Claims7
A transistor for emitting laser with a fixed frequency, comprising:
- a first region;
- a second region;
- at least one quantum well installed in the second region;
- and
- a third region, wherein the second region is coupled between the first region and the third region;
- wherein when a first DC (direct current) bias is coupled between the first region and the second region and a second DC bias is coupled between the second region and the third region to make the transistor operate normally, one of the first region, the second region, and the third region receives two signals from outside of the transistor, or two of the first region, the second region, and the third region receive the two signals respectively from the outside of the transistor to make the at least one quantum well emit the laser with the fixed frequency, wherein the first DC bias and the second DC bias are different from the two signals, and the two signals are two voltage signals, or two current signals, or one voltage signal and one current signal.
