The stripline circulator: theory and practice

Stripline circulator concept and functions from the world's premier authority The stripline junction circulator is a distinct three-port non-reciprocal microwave junction used to attach a unmarried antenna to either a transmitter and a receiver. Its operation is determined by the interplay among an electron spin in a certainly magnetized insulator with an alternating radio frequency magnetic box.

Sample text

The carrier velocity is modulated by the received THz field as well, since v(t) ∼ ????UTHz (t) ∼ ETHz cos(????THz t + ????). 38) < I > ∼ < UTHz (t)PL (t) > ∼ ETHz PL cos ????, where the brackets stand for the time average of the quantities. The phase, ????, is due to a finite delay, for instance by different optical path lengths, d, between the optical and the THz wave, that is, ???? = kTHz d. The photoconductor is therefore a homodyne mixer where both field amplitude and phase are detectable. In a similar fashion, photoconductors can be used as detectors in pulsed systems.

For the total current, holes and electrons have to be considered. Since the formulas are formally the same for both carrier types, we will restrict our treatment to electrons only. However, holes feature a larger effective mass and do not show any velocity overshoot, resulting in smaller values for v⃗(⃗r, t − t′ ). Consequently, the contribution of hole currents is usually smaller. 4. 23) where A is the device cross-section where the optical power, PL (⃗r, t − ????) = exp(−????z)PL,0 (x, y, t − ????), is distributed, and ???? is the absorption coefficient of the photoconductor.

This fact explains why materials with a short lifetime are so successful in the THz range as compared to materials with a long lifetime: they can tolerate much higher optical power levels due to reduced Joule heating. For p-i-n diodes, Joule heating is less dramatic than 22 Semiconductor Terahertz Technology for photoconductors, since little external bias, UDC , is required during operation. Heating by absorbed laser power is more important. P-i-n diode-based photomixers are typically operated under reverse bias.
