VCSEL Bragg reflector with negative index

Hi I am an electronic engineer and a lecturer in a reputed university. I do have experience in filter and this will be another challenging goal for me... I feel really esteemed that I have been invited by you to bid on this project. Your project description provides a generic idea what is to be done. Please send me the detailed specifications then we will discuss it further... Please note that the bid value and the number of days set are set as default. We will have to negotiate both of these things. Again thank you so much for sending me this invitation. Please contact me whenever it is possible for you. Shabbir
