Graded-index separate confinement double heterostructure (GRIN-SCH) InGaAs/GaAs lasers with various cavity lengths were tested in the lab. The 100m wide oxide strip lasers consists of two pairs of 10nm In0.2Ga0.8As quantum-well (QW). The barriers of the lasers are 10nm GaAs (undoped). The lasers give a lasing wavelength around 970nm at room temperature. The refractive index of the active InGaAs layer is 3.4.
Design a wafer structure for the laser. Sketch the bandgap diagram of the laser.
Design an ionospheric radio link over a distance of 2500 Km given that the ionosphere effective height is 275 Km and the electron density N= 2*1011 /m3, namely find : i- the angle of incidence on the ionospheric layer.
The input to a certain filter is given by Vin(t)=2cos(10000pi*t-15deg) and the steady state output is given by Vout(t)=5cos(10000pi*t+25deg). Determine the (complex) value of the transfer function of the filter for f=5000 Hz.
An Electric Range top burner control adjusts the duty cycle of the current and voltage supplied to surface heating element as a function of the control's dial setting. The range controller operates from a 240 VRMS single phase supply
A capacitor of value C=10 uF(microfarads: where 1 uF=10^-6 F) has a voltage of 2 volts across it. Calculate the amount of charge Q,in coulombs,on each plate.
Compare the capacities of the fiber and conducting cables. How many of the conducting cables are required to equal the capacity of the fiber cable.
the diff amp pf has Av= 360 lin(bias)=600nA,lin(off) =100nA and Vin(off)=1mV. what is the output error voltage if a matching base resistor is used, what is the output error voltage
Each subconductor's radius is 10 cm. There are two configurations, the first one is setting subconductors A and B as a bundle, and C and D as another bundle; the second is setting subconductors A and C as a bundle, and B and D as another bundle.
Raffle de St. Michelle: A local charity holds a raffle every year. They have one first prize of $500, four second prizes of $100 each and ten third prizes of $50 each. This year they sold 300 tickets. (a) If you buy one ticket, what amount will you..
