In this work, we propose a set of photonics devices that can be employed as part of optical communications systems. These devices consist of an isolator, a circulator, a multiplexer and a pump concentrator, and are based on the functionality of an optical paraboloidal mirror. The devices were first studied using software for optical modeling and then were experimentally tested. For the cases of the isolator and the circulator, we obtained numerically roughly 50 dB of isolation. Furthermore, we proposed a simple and a novel multi channel multiplexing device, and finally, we asses the alternative and elegant way of the combination of high power multimode diode laser to increase the power capability of diode laser systems that are commonly used in high power fiber laser. In all the cases, the design showed the advantage of the easiness of alignment and the simplicity to implement.
