Query: Outstanding Book on Photonics for all Levels

I currently lead an industrial R&D group in the area of optical device physics. However, I am new to this field and need good background information along with treatises on the state of the art in optics/photonics science and technology. "Fundamentals of Photonics" (Saleh and Teich) has not only admirably met this need for me but I find it to be one of the best written science texts I have ever read! SIMPLY OUTSTANDING!
