Abstract
A monolithic integrated component (10) comprises a plurality of sections (21, 22) including a section (21) constituting a laser having a cavity delimited by a partially reflecting reflector and at least one other section (22) adjacent said laser section (21). The partially reflecting reflector (11) is disposed between the laser section (21) and one of the adjacent sections (22) and is a Bragg reflector grating (11) that allows multimode operation of the laser (21).
Claims11
A monolithic integrated component comprising:
- a laser section having a cavity delimited by a mirror face and by a Bragg reflector grating, wherein the mirror face is an external face of the monolithic integrated component;
- and
- a second section disposed adjacent said laser section, wherein the positioning of the Bragg reflector grating between the laser section and said second section and the construction of the Bragg reflector grating allows multimode operation of the laser.
A monolithic integrated component, comprising:
- a laser section having a cavity defined by a Bragg reflector grating and a mirror face, the Bragg reflector grating constructed and arranged to have a flat reflectivity response at the operating wavelength of the laser section, and the mirror face an external face of the monolithic integrated component;
- and
- an electro-optical modulator disposed adjacent the laser section, wherein the arrangement of the Bragg reflector grating between the laser section and the electra-optical modulator allows multimode operation of the laser section.
A monolithic integrated component, comprising:
- a laser section having a cavity defined by a Bragg reflector grating and a mirror face, wherein the mirror face is an external face of the monolithic integrated component;
- and
- a second section disposed adjacent the laser section, wherein the position of the Bragg reflector grating between the laser section and the second section in conjunction with a predetermined bandwidth of the Bragg reflector grating allows multimode operation of the laser section.
