    Dear Mohammad
    If you are using an older evaluation version than optisystems 16 e.g optisystem 14, then download a newer version like 15 or 16 and your project file will be opened in both of these versions i.e 15 and 16

    I also also understand that Mr Adnan is asking about how to design logic gates using nonlinear effects. The answer of Sir Ahmad is appropriate. For instance, an all-optical inverter is easily can be implemented using XGM in SOA. A lot of literature can be found easily using digital libraries.

    Sir i have drawn a LI curve at 1 Gbps data, Modulation peak current =10mA, Bias current sweeps from 0 to 25mA. I gets a circular type curve as shown in Fig attached. How to get a linear straight curve like DML laser so that VCSEL can be biased at middle of this linear region?

    Please sir tell me, in order to operate VCSELs like DMLs, we have to find its LI characteristics curve and then bias it at the half of the middle point of the LI curve?

    Dear Sir

    Thanks for your reply. As i have worked over optical communication over multimode fiber (MMF), i just need to know how to mathematically write LP modes in MMF. The optiwave tutorials well explain working over MMF but not give required information. If you have relevant literature, do share with me sir.
    I will be very thankful

    can we use each of these equally spaced tones as separate carriers for data modulation like we previously used coherent carriers generated after direct modulation of LD by RF sine signal?
